Hey guys, I'm currently running an XFX 7600 GT card. http://www.newegg.com/Product/Product.asp?Item=N82E16814150140 Its not a bad card but it's somtimes lacking in my Racing Sims. My question is if i'm getting say 50fps in my racing sim with one card, what gains can I expect to see going SLi? To keep it simple for your answer, I will use exactly the same graphics setting with two cards. Is there an ATi card out there that will destroy this SLi configuration under $350? Because that's what my SLi config will cost me if I decide to go that route. Thanks !
