omg that sucks ok so what about if i sli the 6600gt with my dad's old 5700le wouldnt that be a pretty good performance increase the reason i ask is my dad can either sell it for 50 bucks or i can get it for free and i figure that card is worth wayyy more than 50 dollars so if i can use it i'll be getting a really good deal i just dont know how well the cards sli with one another and also mr switch is a ******canoe so if you can just let me know what to do with the sli stuff and if i need a special power supply for the sli
