I currently have an Asus m5 a97 r2.0 motherboard with 2 pcie x16 slots ( one in x16 on in x4). I now have a Superclocked Gtx 660 in my first pcie slot. Would it be worth it, performance wise, to get another superclocked 660, or even a regular 660? How much of an increase do you think I would see? How severly would the x4 slot effect the 660? Opinions on the matter?
