I got any question. I have a BFG 8800 GTX graphics card,but I will upgrade my motherboard to SLI (the new motherboard had some I needed that old motherboard didn't have), would be worth be a second BFG 8800 GTX for SLI? I do play at a 1680 x 1050 resolution. I know it be worth if I had a 1900 x 1200, but not so sure about 1680 x 1050. Thanks for any opinions....
