Which is better dual 6600GT, or single 6800GS
configuring a new pc and already have the SLI motherboard, but not sure that i want to spend th $ for two 6800GS, just yet. So I am thinking of using dual 6600GT instead. If a single 6800GS (PCI-e) will be comparable or even close, then i would prefer to that and purchase a second one later on.
any suggetsions are welcome
