I just wanted to know what effect upgrading my current 4 gb Ram kit to 8 gb will have on performance? Gaming? Currently im running on the Windows 7 Ultimate 64-bit OS. My Ram is Corsair 1333 MHz BUS Value Select (2x2gb) kit. I can just see gaming requirements going up gradually as far as Ram is concerned and its relatively quite an inexpensive upgrade but will I experience quite a noticeable change?
