Hey everyone. I felt like getting something for my computer, and I want to upgrade either one of these two things, my processor, or buy a second graphics card for SLI. I currently have a Q6600 B3 at 3.0GHz at 1.39 Vcore, and a GTX 260 with 700/1475/1260 clocks. Now my question is, would buying a second graphics card and OC'ing it, or would buying a Q9550 and overclocking it to say 3.4GHz give me better benchmarking results? I think a second GPU would, but can my current processor handle it without bottlenecking? Or would a Q9550 make me happier? Thanks!
