I just recently upgraded my MoBo and Processor from a AMD Phenom II quad and a cheap 80$ budget motherboard to an i5-3570k with a $230~ z77 MoBo a month ago, and already I wanted to upgrade the GPU to a PCI-E 3 graphics card. I know where the prices are for the cards, but I currently have a 560 GTX (not TI) installed and I wanted to make myself a little future proof. Depending on the circumstances, I could get two cards and SLI, but currently I am only looking at one.
My question is, which of the current PCI-E x3 cards are the best on the market currently?
