actually... That's the MSRP. :p

Not that expensive anyway... That's how much 2 normal HD 3870s cost.

And two normal 3870s will outperform one of these in every way. If you absolutely don't want to go crossfire, I suppose this is a good deal. Frankly though, today's games and resolutions just do not benefit from 1GB VRAM. Quadros and FireGL cards have massive amounts of memory for good reason, but for gaming performance cards, it's just not necessary right now.

The 1GB ram is marketing speak. Each card is not actually using 1GB...each uses 512mb only...like normal Crossfire. So this should be actually called 3870x2 512mb.

Oh god I'm an idiot. The early beers got to my head and I missed the "x2" part of the title. :laugh:

Then what you need are several late beers to balance it all out. :laugh:

Well, might save you from having to buy a new motherboard, or more expensive one as cheaper P965/P35 boards are 16x4.

"That's how much 2 normal HD 3870s cost"
And to my understanding, in crossfire 2x3870 performs as well as a 8800GT.
8800GT is $300 lets say (lets be realistic here people. pricegrabber'd 8800GT 512MB, $262 was the cheapest I got, oh well. That galaxy would end up being $235 for me, woo hoo. I stopped keeping track of prices after I got mine, what's done is done.). So $510 is a rip off. Unless it was 2x3850 that = 1 8800GT(see my disclaimer?? Thinking back, I beileve it was 2x3850)... anywho, bad deal i say. But ATi fanboys wont care.
"The 1GB ram is marketing speak. Each card is not actually using 1GB...each uses 512mb only...like normal Crossfire. So this should be actually called 3870x2 512mb."
Googleing HD3870X2 1G gave me nothing but asian sites, so googled HD3870
I think (according to http://www.bit-tech.net/hardwa...phire_radeon_hd_3870/2 ) the 3870 has a 256-bit memory bus, so 1GB is overkill (marketing scam). But why do you say the 3870x2 only really has 512MB? Any article stating/showing that to be the case (each core gets 512MB)? Moot point, oh well.

um, yeah. 2x3870 is quite a bit better than an 8800gt in any titles that can actually take advantage of xfire. The problem is finding titles that run properly with it enabled.

You don't want to compare an 8800gt to a 3870 xfire setup, anyway. The 8800gt will hold it's own just fine at lower resolutions, but let's be real here. If you're gaming at 1680x1050 then you don't need more than one video card. If you're gaming at 19x12 or 25x16 then you'll see quite a bit of difference between 8800gt and 3870x2 or 3870 crossfire.

I was under the impression that two HD3870s thrash an 8800GT. And if 8800GTs cost as much as you say (as you said, "Let's be realistic here"), then you need better computer part sources. :)

the GT currently costs 230-250$ (brand dependant) and that is WITH (or you can go without) a quality third party heatsink.
The GTS costs 290-310$...

Just gotta check the online sellers first...

http://forums.anandtech.com/me...=2146375&enterthread=y

anyways, cost and power wise, I would compare the 3870 to two 8800GT cards... Two 8800GT cards + extra cost of SLI mobo over a non SLI one is still less then the MSRP of the 3870x2

However, if you already own a motherboard, the cost of replacing it is higher then the incremental cost of buying an SLI board to begin with. So it might make more sense to get an x2 or GX2.
IE, if you own a non SLI 100$ mobo and replace it with a 150$ mobo with SLI you paid 250$ total, with the incremental cost to get GT in SLI being 150$ for motherboard...
If you just bought them together, then you paid 150$ for a mobo instead of 100$, so the incremental cost to get GT in SLI is only 50$.

Where can you get 2 GTs and a SLI motherboard for $450? Or do you mean the difference in buying a SLI m/b versus non-SLI?

Just 2 GTs will cost more than a 3870X2.

Your misunderstanding is nVidia biased, a Radeon HD 3870 is between 15% and 20% slower than a 8800GT, the Radeon HD architecture performance is erratic, it can be as fast as a 8800GTS, and sometimes, even slower than a GTS 320MB, a Radeon HD 3870 X2 is 30% faster average than a 8800 Ultra in games where Crossfire works, in the ones that doens't work still being at least as fast as a 8800GT, and sometimes slighly slower.

Just 2 GTs will cost more than a 3870X2.

I meant the difference in cost. not replacing the mobo, but buying SLI to begin with for a little more.

And there are various places... I heard microcenter has a 215 GT... and I have seen a 215 after 20$ MIR one online.
But I heard its stuck at 100% fan speed (2 wires for fan).

If you want the asus/palit one its gonna be 250 each. But right now the x2 sells for 550 isn't it?
