:lol: good stuff.

the next company that comes out with an upgradable GPU card wins the war....no more buying new cards. Take out old GPU, buy/insert new GPU :p

More likely the new $300 - 450 card may be faster than 6800 SLI.

Also, a person can add the second card at any time, at whatever price they want, $350, 300, 250, .... without needing to wait for the next model year when the 7800 cards really come out (months after the paper launch).

excellent idea..problem is the ram and other items that run on voltage and such. you'd basically have to build a mini motherboard and it'd be rather expensive and just add on cost. I can't believe people have been paying $500 for video cards as is

How about the fact that you dont have to buy both video cards at once .. IE ... but a 6600 GT ... then in a year or so .. when it starts to feel slow, double up on it ....

I agree its stupid to go SLI right off the bat, however, the upgrade path seems MUCH better for the SLI capable cards ...

I'm not sure, but I think the higher the resolution goes, the more the SLI solution will pull away from the single card solution. We'll have to wait for some hard test data though.

Not to mention that going SLI means:

1. mobo upgrade (add more $$$ here)
2. more power comsumption (add more $$$ here)
3. total cost to go SLI is > $390.

why would anyone go SLI? I think this is a huge error on nVidia's part....SLI should be for their Top performing card only. This way, it forces the people to buy into this solution if they want the fastest and the best. If SLI is available for low and high end cards...it makes the technology look "retarded" the the company look greedy.

What do you think?

I agree with you. Although we have very limited information to work with, I will not be purchasing an SLI board, just single PCI-E. Just by the numbers posted by Anand (which came from Nvidia site BTW), 6600GT SLI does not seem to justify the cost vs single 6800GT since it only has minimal frame rate advantage. In addition, more powerful cards will come out which will supplant the current line ups anyways. Lastly, for my personal use, I don't need 150FPS. I will be happy with 60FPS :)

However, I don't think it is a huge error on Nvidia's part. SLI will be trendy and they will rake in mega bucks from this. I just think it does not makes sense for me financially/performance level.

I say hooray for upgradablity, one card now, one card later makes me happy. Also, I know many people have beef with 3dMark 05, but so far 3dmark 03 and 01 have gained popularity over time and have been reasonable indicators of current and future gaming performance. 6600gt's in SLI beat out 6800ultra for future games I say.

You can always get an x800xt pe, use exotic cooling and blow 2 Ultras away; at least in 3dMark05.

Like SMP systems and RAID, SLI is not designed to benefit the lowend, it's designed to extend the highend. Almost no one will benefit from buying a system with 2 lowend CPU's that cost the same as a top of the line single CPU system if not more. If you're not going to go all out and destroy the bank by going with only the highend, then you shouldn't be looking at SLI, SMP or RAID because you are unlikely to see any improvements over cheaper single solutions. It's unlikely we're going to see any single video cards competing with an SLI 6800 Ultra for quite some time. How long did it take before a video card to beat a 9700Pro by 85% in anything? 2 years? That's an eternity in the computing world.

There are also legitimate uses for this technology in industry where the extreme performance is actually needed by some. This technology being adopted to the Quadro line will definitely win NVidia some contracts in the corporate world where time and performance is money, not about bragging rights.

LMAO....wtf are YOU talking about....look at the numbers man....

6600GT doom3 - 17.3
6600GT doom3 SLI - 32
6800GT doom3 - 37.9

6600GT halo - 37.23
6600GT halo SLI - 58.58
6800GT halo - 50.01

tell me that's not just under or about the same...

do you work for nVidia? cuz I'm just trying to strike up conversation about something that is painfully obviously to anyone with 50+ IQ... :roll:

How about you read what i edited, i listed the wrong numbers by accident. You're not comparing cards that are the same. Check the differences in the 6800 SLI and GT Single. If you don't think a 45-80% performance difference is a lot...i dunno what to tell you.

and you are not reading my original post.....do you see the all important factor of $$$? There's no doubt that SLI kicks single card's butt, but is that what I'm talking about? No, I'm talking about paying more for a solution that performs about the same...that's what I'm talking about. I alsmo mentioned something about SLI for the top performing card only? Did you read that part? Because it discussed why SLI for a low end model is retarded...



What if we bought just one 6600gt. Just to get by with currently decent performance, nvidia launches its all new 6900 or something blah blah blah, 6600 gt now costs 120 or so, Would it be cheaper to go out and get a whole new card, or get another 6600 gt and get the same, if not more performance, those numbers you see arent all Nvidia can do, there will be performance increases over time as the sli drivers mature. Maybe you shouldnt be such a douche bag imho

That page from Anandtech You linked to shows that an 6600GT in SLI beats a single 6800Ultra in both Halo and 3DMark05..

You know why it's slow in Doom3?? They've decided to run it @ 1600x1200 on a 128Mb 6600GT..
Run this benchmark on 1280x1024 and the 6600GT's (SLI) are easily faster then the 6800GT
As you can see in this review.

So YES, SLI really does matter, also for the 'low-end' cards. But ofcourse, the best solution would be buy one 6800GT now, and wait untill an upgrade is needed and buy a second one, cheap!

But you're right about higher power consumpsion, that and heat will be a problem when running two 6800GT's or Ultra's together.

[edit]

In DOOM3 the performace gain in SLI is 85%.

Anandtech shows that a single 6600GT produces 41.9 FPS @ 1024x768 4xAA and the 6800Ultra 73.1FPS

41.9*1,85 (185%) = 77,515FPS

But even when SLI performes 75% higher in DOOM3 the 6600GT SLI would be faster then one 6800Ultra.

you have to realize that SLI is targeted for the "enthusiasts" People that are willing to drop 2 6800Ultras in, or 2 6800GT's. NV is adding them to all there PCI-E cards it seems and is TRYING to target the casual gamers, but again, SLI is probably more suited for the big buck spenders. Intelligent consumers will note that a 6800gt will either outperform or be on par with a 6600GT SLI set...but theres always a niche of people that need bleeding edge technology.

seems like due to heat density issues, SLI/dual processor will be in the future for high performance. the days of 1 CPU+1 GPU are coming to a close. The days of multi-cpu+multi-gpu are neigh.

Wow, has there ever been a piece of technology that you CAN'T EVEN BUY YET that has generated this much controversy and harsh feelings? Personally, I think SLI is sweet. Is it for everyone? No. If you're one of those people, simple-don't buy it. Who cares? It's not like you're being FORCED into it. But some people might want it, so why the incessant posts about how much it "sucks"???

Where the hell are you getting a 6800GT for $340?

Where did you come to the conclusion the 6600sli'd performance is the same as the GT when it beats the Ultra in two benchmarks?

How much is an Ultra compared to 6600gt's in sli? mmm.. sli comes out cheaper, not more expensive.

I didn't know technology could look retarded, but you do have a way with your reasoning. :roll:

Here's the point of SLI...

2 6800 GT's in SLI or
2 6800 Ultra's in SLI

65-85% improvement in performance from one card ==> two cards

Nuff said.

Those who have the money pay for SLI and two cards...those who don't have the money stop whining and get over it and get a NF4-Vanilla/Ultra.....Not saying I have the money for SLI set up though :(

Of course it doesn't make sense to you because you can't answer the questions or back up what you've said.

What's the point? Quite.

By the time you actually need the horsepower of that extra 6600 or 6800GT in SLI mode, will you actually want one, or will you want the extra features of nv50 or whatever's next.

Think about it this way. By the time the 6800 series was becoming available there were few titles that were really making a 9800pro struggle except at high resolutions with AA. If you could have SLI'd 9800pros, would you have bought another one at that point, or just got a 6800GT which is twice as fast anyway and has new features like SM3.0 etc.

All this is about is bragging rights, for nVidia and for rich kiddies who can't tolerate less than 60fps at 1600x1200 with 16AF + 8xAA.

Well the cost benefit comes in if you wait for prices to drop significantly before ponying up for the 2nd card.

Lets say a 6800GT is $400
Now let's say a 6600GT is $200, but then you wait until the 6600GT goes down to $150 before getting the 2nd card. That'd be $350 for the SLI.

6800GT = 400
6600SLI = 350

so the SLI could be cheaper and faster. But the trick is you get only half the performance now and half later with the SLI route. With the 6800GT you get all the benefit now.

Not to mention by the time you're ready to plunk down for the 2nd 6600GT, newer faster cards with new features might likely be out. Shader Model 4.x or something like that. Also higher clocked cores and or memory or DDR 4 or 5 or whatever is out by then, who knows?

When he states $340, I believe he is just rounding off the price, not the actual as seen here.

Newegg(an example I hate to use) is selling the Chaintech for $198. If you were to add those 2, It comes out to $396, roughly 400.

His theroy of the 66k SLI being just about the same of a single 68k seem (genere:FPS wise) to have a point. Value wise. IMO atleast, I could be wrong.

That's a 128MB card. Not the 256MB GDDR3 memory.
