I'm building a new rig and I'm wondering what's better for the money. 2 NVIDIA 7900 GTs in SLI or a single 7900 GTX or perhaps something else?
 
well the 7900GT SLI is pretty much as fast as the 7900GTX SLI anyways, so I would say save some cash and get the GTs.
 
Everything I've seen says buying a single GTX is cheaper than buying two GTs, is the performance of a single GTX the same as two GTs?
 
I'd get one GTX like I did. So you can do GTX SLI later one without having to ditch 2 cards somehow.
 
7900GTX means no need to get an SLI board if you don't have one. It also has 512MB. I don't think having two 256MB cards bumps actual texture memory to 512MB in SLI, does it? Just each card has 256MB still, not 512MB pooled, right?

Correct, and SLI requires a profile, and doesn't always boost performance in every game.

Single card works well with everything. SLI doesn't.

Well there's a difference between spending 600 and at least 1000 dollars bud. Now the reviews are showing SLI'd 7900gts mop the floor with a single 7900gtx anywhere from like 10-30fps. Don't kill the messenger on this one.
 
I would definitely go with a single GTX. SLI still has it's issues.

Or just buy a single 7900 GT, that will be great for a long time too.

Umm yeah, I know the difference between $600 and $1000. Thanks.
 
Would I be better off buying the 7900 GT instead of the GTX and spending the other money somewhere else like better RAM or upgrade the 3.0 Pentium D I'm planning on to the 3.2?

I'm always a big advocate of getting the "second best" hardware when upgrading. You tend to save about half an only lose about 10-20% performance, if that. I think you'd be pretty durn happy with a gt. But hey, if you've got the money and the desire its always nice to know you have the best.

RAM would help, but going from 3.0 to 3.2 isn't going to really matter that much. If you can get one of the 65nm parts, they've been apparently overclocking like mad.

no two 7900GT's would blow a 7900GTX out of the water, I ran two 7800GT's and got 10,000 3dmarks in 05 with no oc, a 7800GTX only got 8200 3dmarks that should give u an idea
 
read up oin dx 10 and windows vista before building a new rig nothing thats is out right now is going to run vista they way its suppost to run not even 30in dell lcd monitors

Um no, one 7900GTX performs a simular gaming experience as 7900GT SLI, although the two gts generally get 40-60% more performance then the single gtx.

Although for only 10% more price its worth it to go the 7900GT SLI rig, better bang/buck.
