2 6800gs = 1 7900?

post #1 of 17
Thread Starter 
Trying to decide if I want to get a new 7900 or just do 2 6800GS. I already have 1 6800GS. Any thoughts?

the 7900 (single card) is alot better than two of those 6800gs's in sli..|

to be honest, SLI doesnt offer that much of a performance boost. Example: 2x 6800GT's vs 1x 7800GT

The 7800GT would be better, and the price would be much cheaper as well.

It depends on what 7900 you are talking about. A 7900GS gets beaten by two 6800GSs in many benchmarks. All other 7900s are more powerful.

Sounds like you got the answer, but just to second it: A single card of one generation is generally better than 2 cards in SLI/X-fire of the previous generation.

thats not always true, two 6800GS's are faster than a single 7800GT, and that makes them about 6-8% slower than a 7900GT and about 1-2% faster than the 7900GS. If you already have a 6800GS, get another 6800GS its cheaper and it will almost be as fast.

just do what's cheapest. DX10 is right here, and you shouldn't be spending all yoru money on DX9 hardware.
