If i buy this card, will i have any trouble running the 256-P2-N583-AR with the 256-P2-N563-AX.
they both are 7900gt's and both have 256mb but different model numbers.
For SLI to work correctly, I think all you need is two cards from the same family/chip. Don't quote me on this, and I don't run SLI myself, but I thought I read this on the nVidia website before. Hopefully that'll point you in the right direction.
@travislefler, Any 7900GT from any manufacture will work in Sli, I run an Asus and an XFX together and take no notice of Maziar's comment, as I run @ 1280x1024 and there is a difference between Sli and non Sli.
go and see some benchs ,SLI shines in 1920x1200 and higher , i dont mean SLI wont make a differenece at all in lower resolutions , but as i said it will mostly shines in 1920x1200 and higher , the difference gap between SLI cards in lower resolutions is alot lower than higher resolutions ,thats what i wanted to say
I upgradded to a 7900 GT SLI in August. I couldn't have been happier. I saw about a 20-35 FPS improvement along with a huge increase in minimum FPS. The SLI also allowed to get better results when using AA and AF. I run at 1280X1024 btw.
