I have the MSI 790FX-GD70 mobo and I would like to run one or two (ATI 100-505556 FirePro V8750 2GB GDDR5 PCI Express 2.0 x16) and two of these (HIS H597F2GDG Radeon HD 5970 (Hemlock) 2GB 512 (256 x 2)-bit GDDR5 PCI Express 2.0 x16) Im going Solid State with a 1200watt PSU. And the AMD Phenom II X4 965 Black Edition 3.4GHz. I would like to overclock and I am looking at the 4gb sticks of DDR3. What would be the best configuration for optimal performance and stable Over Clocking?
