I have a 512mb version of the HD 3850, so it's practically the same card as a HD 3870. Its a very good card, runs TF2 great. The only thing is AA really kills your FPS, its a known thing with ATI cards. So I only run 2X AA because the extra performance hit isn't worth it.

My 3850 handles AA with no real performance hit. At least not one that I've noticed.
I normally play at 1280@1024 with highest setting and highest MSAA (Mind you I don't understand the technical details between MSAA and FSAA, so that might have something to do with my performance) and it still blazes along at around 50-60 FPS.
Also, Doobs is completely correct about the backwards and forwards compatibility; my mobo only supports PCIe 1.1 and the 3850 is PCIe 2.0, and it still works just great!

PCI-e 2.0 is completely backwards compatible, btw. You just won't get the full benefit of a PCI-e 2.0 card if you don't have a PCI-e 2.0 motherboard. I can guarantee that an 8800 will work if a 3870 will work.
