Reviving a old thread, I'm sorry. I recently got back to my project of upgrading this PC. I've done some more research. This is the board I have http://www.asus.com/Motherboards/AMD_AM3/M4A78LTM/#CPUS
I'm looking at buying a Phenom IIX6 1090T which according to asus is supported by this board.
I understand one of you believes my PSU is not very great. Still think it will be a problem upgrading to the 125w cpu?
I've talked to some others who say it won't be a problem. I assume my current CPU which is the 220 x2 regor is a 95w. Anyways let me know. Also; do i update the bios before I install the new CPU or after?
