I am thinking of replacing my two 8800GT 1Gb in SLI with a single GeForce GTX 570. Leaving the DX11 factor out of the question, would that be coinsidered a step down in overall performance? or a step up? With the issues some games that I play have with not supporting SLI or XFire I was thinking it may be better for the time being to step back to a single card configuration, or posibly retaining one of the 8800GT cards to dedicate to phisics???
The GTX570 as a single card is still much stronger than a 8800gt SLI.A single card is always better than a multiple setup as most games don't supprot SLI and the hastle of drivers working or not for a multiple setup.
I hear you there, and you are correct about the 560 being better in SLI, but as most of the games I play do not support SLI the 570 has enough of a performance edge to go that route and there are several on the market with after market coolers that bring the temps inline with the 560... Also, the two 560s in SLI will run you close to $500 where I can get a good 570 for $350.
SLI has come a long way since a few years ago. Almost every game benefits now from SLI and CF. However, 2 8800GT's in SLI will not compare to a single GTX570. BTW 2 GTX570 would destroy 2 GTX560's. SLI scales very well with all new cards.
It would be a step up about 50-60%.
For example 8800GT=9800GT=X2=9800GX2 which is about 50% slower than the 570.
Ummm, I don't know if those numbers would hold up.... I upgraded to a GTX 570 from two 8800GT's in SLI and in 3DMark06 I only got a 5.1% increase from 15,819 to 16,629. I know there are new features present but talk about being bummed out.... $300+ was a waste for me in playing Battlefield Bad Company 2....
