In general ATI cards perform much worse than Nvidia cards in FSX, even at CPU bound resolutions, which makes no sense to me, and which even Phil Taylor can't explain, and he is the lead Program Manager for FSX, was a DirectX engineer for a time, as well as a hardware engineer for ATI. So for that reason I would avoid ATI cards for use with FSX.

Here you can see the 8800 Ultra is a full 25% faster than the HD3870 at 1920 with AA.

Other than that FSX doesn't need a graphics card faster than an 8800. I run mine at 1600x1200 with 16xS supersampling and 16xAF and I'm still CPU bound at 3.5GHz. So an 8800 is more than enough power for FSX, and puts the bottleneck squarely on the CPU.
Intel Core i7 920 Nehalem Quad @ 4.0GHz
EVGA GTX 660 SLI @ 1046MHz
OCZ Platinum CL7 6GB
EVGA Intel X58
