I am in need of 8gb RAM DDR2 (4x2gb). I've seen prices ranging from £130 for cheapest and £190 as a mid-high end price. Now, my system is OC'd (Q6600 @ 3.4Ghz) and I'd like to keep it that way. With the cheaper RAM (happens to be Dell ram), will I still be able to keep this same OC? How much does the quality and speed of RAM matter? Realistically, are we talking just seconds of time saving between low-end RAM and high-end RAM? What difference does the quality of parts make?
