Wondering if there are any obvious upgrades appropriate for my system, which hasn't changed in the 4 years since I built it. Cooling/system gets noisy playing some games (alien isolation on max settings for example) but not sure if that's gphx or cpu. Current system is; Asus P8P67 mobo i7 2600K running stock at 3.4Ghz - not overclocked 16GB mem W7 64 bit 256 SSD 1TB HDD (enough space left) MSI GTX570 1.2GB Any obvious changes/upgrades? Thinking about W10 too when the dust settles AFTER its initial release. Any thoughts welcome...! Thanks.
