Right now I am using a Radeon 5770 with Eyefinity, and it is performing admirably for such a little card, I only suffer in high traffic and in the clouds. I've read enough around the forums to know that I need to switch to NVIDIA in order to get decent frame rates in these conditions. (which is sad, as it would be wonderful if an HD 6970 could do the job, since I'd only need the one card) I want to continue to use my triple monitor setup, so I am faced with a conundrum. Should I get a single GTX 580 with TH2GO, or is a pair of GTX570's in Surround going to do better? My primary concern is to achieve the best image quality possible in my sim, and to be able to achieve playable frame rates in other games. Does anybody out there have advice or an opinion on which option is superior?

If you ever concider adding a fourth, touch sensitive, monitor I'd recommend TH2Go. As far as I know Surround on two SLI'd cards wont allow a fourth monitor...so I've heard. Is your PSU up for the job of feeding two GPU's?Bjorn

1. Are you using Bojote's Shader 3.0 fix for ATI cards?2. SLI feeds the stutter monster in for FSX, so don't buy video cards for use with SLI.Cheers,- jahman.

Right now I'm running a 1200W Antec PSU, so I know that multiple cards shouldn't be a problem Jahman, I am running the Shader Mod, which I noticed about doubled my performance in the clouds. Is it possible that with a more powerful ATI card everything would run smoothly? I don't have stuttering problems right now, as long as my FPS are pinned at something the card can manage. I know the 5770 is a featherweight in comparison to something like a 6970, but I'm just concerned about getting the best IQ I can. A 6970 would also be attractive because it would mean buying a single card, cutting my cost in half.

Yeah, Bojote's tweak is impressive!Another advantage of the HD 6970 XT over the 6990 is it runs faster (+6% in the GPU clock and +10% on the VRAM clock).Eventually an AMD card will meet FSX's requirements fully, likely a nextGen 7970, especially if released with PCIe v. 3.0 (2x the BW of PCIe v. 2.0) when teamed with an Ivy Bridge CPU.These days though, for lack of Shader 4.0 use FSX best results are obtained with the nVidia 560 GTX and up.Cheers,- jahman. (That HD 4870X2 with the useless second GPU keeps on chugging... :-)

Why not buy a 6950 and flash it to a 6970?http://forums.anandtech.com/showthread.php?t=2130396I´ve been considering both TH2GO and Nvidia Sorrund, but have finally decided that the best solution or compromise will be Eyefinity.Use Bojotes Vsync fix for AMD, and the Tweaktool..

I'm thinking that I may go that way as well, though I think the 6970 may be the way I go, because of the tighter RAM timings. I've read of problems with flashing the BIOS b/c the ram on the two cards is different. Do you guys think that these cards could brute force FSX into decent performance?
