i have the his x800 pro...(atix800 w/ a huge cooling sys built on) and yeah, the game is very pretty when maxed out, although when the servers lag a bit i get kicked running at max graphics so i run a little below, with some high and some medium
the difference has to do with how many pipelines of pixels are unlocked, either 8 12 or 16 probably
I just built a computer with an Athlon64 3400+ processor, 2Gb of OCZ Platinum RAM, and a Geforce 6600GT graphics card. The game wont arrive until Monday or Tuesday, but I'm seriously dying to see what it looks like.
