Hi guys my first post here although I have lurked on these forums for several months 
My rig is in sig but i have a choice to make. Recently came into a little bit of cash and am very tempted to buy a 8800gtx on Wednesday. My other option would be to go conroe and keep the current graphics card. Given the choice anyone got an opinion on which way to go?
