I have made a wonderful discovery that might possibly solve my problems! Of course, a second opinion would be wonderful. My computer has two PCIe x16 slots. I was reading somewhere on the forums that two GTX460 cards on an SLI setup can make up for the stutters I'm having. It's more affordable at $130 (on Amazon) than going out and buying a higher-end graphics card. So, does anyone agree or see a downside to this setup?
