I am currently running a opteron 144 @2.88 with a Akasa33 cooler. And now i think its about time to change to dual core I have recently bought a Arctic freezer pro and was thinking of just changing the cooler, but i thought why i was there i might aswell change the CPU too. So what do you guys think would be the best cpu change? I would be using it mostly for gaming, and my budget is not to great, but reasonable. Also maybe a stupid ? but could i use DDR2 in my motherboard?
