How many GPUs can be used in the same computer? I've been wondering since the new AMD cards came out. I can't decide if four R9 290 (if 4 is possible) or two R9 290X would result in better performance. This is assuming that all the other variables are the same, obviously.

As many as you can fit on your motherboard, but CF/SLI only go up to 4, and there's not much point going beyond 3, or even 2 tbh. Also, multi-gpu setups are problematic. Single GPU is always going to be more stable and reliable.
