ok i am in the process of building a computer but have reached a dilemma. should i get a XFX 8800GT 256MB XXX + Liquid cooling for my Q6600 (i enjoy overclocking) or should i ditch them both just for a 8800GT 512mb and no liquid cooling. the ones i have in mind total up the same price in GBP. At the moment i only have a x1950 pro so either option is good as an improvement. thanks a lot in advance for any help.
