If I buy two lots (4 sticks) of the G skill ram in the first post (dual channel) will I be able to put them all in my mobo and use them? Or is that only possible with quad channel memory?
There might be a game or two out there, that will gain 1fps or 1.5 fps, heck maybe even 2. But for the most part it won't make a noticable difference unless you are running particular benchmarks. I mean, you can always sell your old ram after you swap - so I say go for it if you want to be as snappy as possible. If you still need SSD drives or other upgrades though, you might hold off.
