An i7 950 @ 4,0 ghz , what gfx card will do best? The lowend 450 or the expensive 570 or 580?Will i get more fps by turning up to those or will the cpu be the only player according to fps?

Why did you post it twice?

450??? Did you mean 460? I think a GTX 470 wound be enough, since FSX is very CPU consuming and the grafic card is not so really inportant, but a 470 is mostly as good a the 480, but costs half of the 480.

No i meant 450I am intended to run it with tripplehead in 3x1920x1080 resolution

Well, if you want to do this, I wouldn´t get the GTS 450, she´s maybe a bit to slow to catch up the CPU speed. It may be the bottleneck. Ok, she´s not really expensive, but I would go for a GTX 470 or 560. The GTS 450 has only 192 CUDA cores, the GTX 470 has 448. It might be better to have more power if you want to drive 3 monitors.

GTX 460 will run TH2Go @ 5040x1050, I got a 2gb edition and overclocked it a bit.Bjorn

To run triple monitors without TH2Go (using nVidia Surround 2D mode), you'll need to run two cards in SLI mode. I just recently made the jump to 3 x 23" 1920x1080 monitors and am running 2 x GTX 480s in SLI mode. This works great for me. I was running a single GTX 480 with a 22" monitor and my frame rates haven't changed much when driving 3 monitors - well, at least not enough to notice.-Jason
