im not sure where you are getting those numbers sam but AMD cpus are garbage atm, they are good for the simple internet user ect.. but they suck for games, nevermind 5x boxin on one computer. infact 99% of the review sites dont even add AMD cpus to the test vs intel anymore because they just get killed so bad.

and im not being a fanboy, i have a ati/amd video card and i love it. but they just arnt upto par with intel atm. buy yourself some cheap used q9550s and some low end p45 boards and overclock them to 3.5-4ghz each. they dont have the ondie memory controler like amd does but they still should put up even numbers in that area.

if you really really want a ondie memory control and a smokein fast chip get some i7920s and OC them to 4ghz. should last you a few years. or atleast till all 26 of your toons are 80 :P
