I have an AMD Quad Phenom 9950 black edition, 8 gigs ram @ 1066, Vista 64, raid 0 velociraptor drives, Nvidia 8800 GTS and with 5 clients I'm lucky to get 12-15 fps on my main in Dalaran with lowest settings on... it's brutal. Any other zone I get 60 fps main, 30 fps on clones no problem. CPU is maxed in Dalaran. Next system will definitely be an Intel...
