Okay, so I built an i7-920 computer about 9 months ago. I'm running 2 GTX 285 in SLI in it currently. I needed another computer of comparable performance, and I decided to build one on the i5 platform this time. I built an i5-750 (which I'm amazed at by the way, overclocks SO EASY to 3.4 ghz and stays under 30C on air) and put in it a pair of 5850's in crossfire. I don't think either of my configurations will bottleneck my video card's performance, but I'm only going to be using one of these setups for gaming. Both are hooked up to comparable monitors of equal resolution (1920X1080). Any advice on which of these setups will be "better" for gaming? I'm assuming the 5850's, although I've never done crossfire before, so I don't know if that setup scales as well as the GTX 285's do in SLI. Thanks for any advice!
Actually, yeah, that's probably my best bet. I guess since I know the GTX 285 and 5850 are very similar in performance my bigger question was which scales better for games, SLI or Crossfire, which a whole other debate. I'm guessing the 5850 will do better, but then again it is also in a slightly "inferior" CPU setup. The results should be interesting.
Just an update, did some testing. On Dirt 2 in particular the results were a bit shocking. I'm running at 1920x1080 btw. My GTX 285 in SLI, everything, I mean every single thing that can be maxed out on that game, I was getting about 70-80 FPS. Very decent performance overall. The 5850 in CF? Around 110 FPS! I wasn't expecting that big of a jump, even taking in to consideration it being a DX11 game. I don't know if it's the gains from the 10.3 drivers or what exactly, but 5850 CF just murders FPS.
