x1800xt - Nvidia equivelant?

I recently posted asking about crossfire...turns out the whole "crossfire edition" master/slave requirement is a bit too esoteric (and expensive) for my liking.

Let's say I went to the other side, nvidia...what is the rough Nividia equivelant to the Radeon x1800xt? And does SLI have any similar master/slave requirements or can you just get two identical cards, toss 'em in an SLI mobo and have fun?
 
With SLI there's no need to buy an overpriced and underperforming master card. You can slap any two cards together (even different brands I think) so long as they use the same chip.

The performance gain isn't all that huge, but hey if you got the money go for it.

Yup, what he said & you can use different brands aslong as the GPU & memory Config is the same. No Mastercard required for SLI.

Comaprative cards:

X1800XT - 7800GTX
X1900GT - 7900GT
 
I thought I heard somewhere that new drivers would allow the x1800xt to run in crossfire without a master-card. I could be completely wrong though... Could someone shed some light on that?

x1800 xt is comparable to the 7900 gt and the radeon x1900 gt.
The x1900 gt still has driver issues which cut it's performance badly.
And there are still quite a few x1800 xt's in the market.
So if u are getting one,i would suggest u get that!!
 
Design a system around a single VGA card solution. You loose all of the second cards onboard memory with either SLI or Crossfire. Why would you want to intentionally do that ?

Get a fast card to start out and make sure it has 512mb to cover you once game mfrs take advantage of the extra onboard memory.

Better still get a X1900XT or 7900GTX and you will likely have those card for many years and not get bored with its performance, and still be far cheaper than a dual VPU system
 
Thanks for the help - now I'm definitely comfortable just spending $300 on a 512MB x1800xt and just being done with it for 2 years or so.
 
i would say save an extra 100 and get the x1900XT It will kill the 1800XT in new(er) games.

The x1800XT already loses to the 7900GT in Oblivion in any res over 1024x768.

link?
Edit, ok I see in that xbit labs article. Look at AT's roundup: they kind of trade benches with the 1800XT doing better in the very stressful Gate benchmark. I didn't really know the lack of shaders held the 1800 back so much, even at 1280...

I believe that is true...someone here on these forums had an X1800XL Crossfire setup using no master card but that was with beta 6.4 cats I think. However, I don't think anyone has done any quantitative measurement of the performance impact of running Crossifire over the PCI-e bus.

Maybe if you have a motherboard with dual x16 PCI-e lanes the impact would be reduced??? Dunno but I'd be interested to see the results.

I need to see that. Ati's site still shows that you need a master card though.

If you can use any two 1800XT's to run CF, I'm on it.
