Hey guys, just moved into a new bedsit and electric's on the meter! Currently running a 920 D0 @ 3.4Ghz, RIII Gene, 6gb G-Skill Trident ram, 2 HDD's, GTX 460 OC 1gb, 60gb SSD. Was wondering, if going to sandybridge would be worth it on the leccy bill? mainly switching mobo/cpu/ram. any tips, please let me know!
