I'm thinking about selling my current setup to upgrade to i5-2500k and stick with that build for a few years. My current setup is way too loud, and the components are the worst above average tier, which I won't be able to sell in 2 years anymore.

Current:
CPU AMD2+ Phenom™ II X4 940 @3.4Ghz
CPU Fan FREEZER 64 PRO PWM
Case MIDI LC-Power 7004BII
PSU 600Watt OCZ StealthXStream 80+
VideoCard AMD Radeon 6850 Sapphire
Motherboard Gigabyte GA-MA790X-UD3P
RAM GeIL DDR2 Ultra PC2-6400 800Mhz Dual Channel Kit @ 4-5-4-4-12


Upgraded
