Well I play a lot hah but its mostly WoW, not very serious I know, but Ive been playing Supreme Commander online more often now and I find I get laggy as more and more units get made. I dont know how to overclock my CPU but if its not going to ruin anything Id be willing to do it, as for money I'm not sure if you have a few in mind just toss em out there, nothing crazy like 500$.
