you need a minimum of windows vista, 7 is recommended. plus you only will need 1 of toughs cpu's for gaming so go into bios and turn 1 off. pointless running the cpu when its not gonna be used.
and it is only a 2.0ghz cpu so you may want to oc it to 2.6 or more if you can...
thank you both for the input!! i do have windows 7 ultimate sp1...do you have any suggestions on what program i should use to oc my cpu?
