I heard that the increase in performance from having more than a single GPU are not extremely significant. Having TWO graphics cards in CF/SLI does not necessarily mean double the performance. Although some benchmarks, especially Far Cry 2 show an almost double increase in framerate using Two enthusiast GPU's in CF/SLI.
A single HD 5870 will run Crysis smoothly, Two of them in CF will not double the framerate, but maybe increase it by 10-15 fps in most cases. Unless you're trying to run a game at extremely high resolutions with the AA turned up, Two, Three, or Four GPU's are not essential. Not to mention having to have a beefy and costly power supply.
Some games benefit differently from a multi-gpu setup. Some like FC2 show significant performance gains, while Crysis and the STALKER games only show a minor increase.
FC2 looks graphically equal, if not better than Crysis. Why does is it so much easier to run at high settings than Crysis?
