My current computer is an old P4 machine, which cannot cut it anymore in World of Warcraft after I upgraded to a new 22" LCD. I want a machine which can run WoW above 60fps with medium to high settings on a monitor with resolution of 1650x1080. I am trying to keep the build under $600. I already have a few parts left over from old builds. An Antec P180 for case, two sticks of 1 GB ddr2 667 Corsair ValueSelect ram, and one or two Sata hard drives. Everything else I will need to buy for the build. I have no clue what components I will need to fulfill my requirement of being under $600 and still being able to play WoW about 60 fps. Help me out here and post what parts I need, overclocking is perfectly fine if it helps me stay under budget.
