what is overclock? lol and also when i put the card in the computer will i need to do anything or will the computer just use the card? lol
It means to raise the cpu clock or/and memory clock, you just need a pcie 16x slot, preferably at least a 2.0 one, i think you'll have one, and a decent psu with 500W and 25A on it's +12v rail, and decent one, will have more than that.
