Tri sli will cost a bit on your electric bill though. I was in the same dilema as you and I ended up going with 295 GTX for my I7 rig. I measure the power usage on my gaming rig. My computer with 24" monitor, speakers, playing Crysis at 1920 x 1200 AAx2 equals no more then 480 watts. VS Tri SLI will use at least 800 watts. Thats just the computer by itself without moitor and speakers.
I'd buy the 295 which will leave you space to upgrade again to another 295 in future.
People speak alot about scaling and going to tri SLi is a very hardcore market and maybe the drivers aren't that optimised. I don't know this for sure so maybe anyone with tri SLi would care to comment?????
2x295 will scale even worse since that's Quad SLi.
Even in games and drivers with good SLi support, the more GPUs you have the greater the diminishing of the return value.
If the 1st GPU is at 100%, then for SLi, the 2nd GPU will maybe get 80% return, the 3rd maybe 60% return, and the 4th GPU might only get 40% return...and this is the best case scenario.
