I agreed kaptkarl.
@Ancient76, The bit about better min. FPS is correct. The 470 does have a higher minimum FPS in nearly all of its examples. However, ATI's drivers are very mature, whereas nvidia's are still new. There are people all over the internet complaining about compatibility issues with the GTX 4xx series. Also, the GTX 470 does NOT have better DX11 performance except for a select couple of games that have been optimized to run on nvidia hardware. Better AA support is subjective. It's able to reach higher levels of AA than the 5870, but the performance hit from that AA is still very real and significant.
Keep it real bud.
