Okay I built this computer. It comes with an AMD FX-4100 Zambezi 3.6GHz Quad-Core and HIS H685FN1GD Radeon HD 6850 video card. Now I just installed 2Gb ddr 3 ram on it and am actually surprised at how good it seems to run with just 2gb ram. Now I am installing 12gb on it but I just want to know, does adding tons of memory make that much difference...and by tons I mean12, 16, 24gb ram vs 8-10gb ram.
