I currently have three systems that I have built over the past year.

Gaming rig:
EVGA 780i
Intel Q9450
2x EVGA 275GTX SC
8 Gigs Ram
WIN7

HTPC:
EVGA 680i
Intel E8400
PNY 8800GT 512MB
4 Gigs Ram
3 dual tuner cards
BluRay/HDDVD combo drive
WIN7

Hackintosh:
GB GA-P35-DS3L
Intel Q6600
EVGA 8800GTS 640MB
4 Gigs Ram
OSX 10.5.4

Currently not in use:
2x EVGA 8800GTX


One thing I have been wondering is if I should move the E8400 into my gaming rig and overclock it or just keep everything the same. What parts would you use where? Any advice would be great. FYI, I am using an Thermalright Ultra-120 Extreme cooler in my gaming rig currently. Thank you
