Okay, so i have a 940 Phenom 2 overclocked to 3.7GHz, and im tired of DDR2 and slow ***, so ima move onto a Intel i7 semi bidget setup, Im useing a EVGA 260GTX GPU, and was wondering what northbridge chipset should i get for fastest gaming speeds. I don't know all that much about chipsets just that i want a fast one, I want sli because i have a 9800GTX i want to try and setup as a PHYX card, no idea how, but im sure i can figure it out. SO for gaming, X58 or 790SLI??
