Im going to be getting a new system soon, and i wanted to take advantage of this new SLI thing(new to me lol). So i was going to buy 2 NVIDIA Geforce 7600 GS 512 MB. But i got to thinking about it and would it actually be more effective? So i looked at a card that would be the same price as buying both of those and its the NVIDIA Geforce 7950 GT 512 MB. Which should i do? It seems like having two 512 MB cards would be more effective but then again the other one is more expensive which probably means its better lol! i dont really know what im talking about.
