this past February, I replaced my motherboard, cpu, and ram.
Motherboard: ASUS M4A79T Deluxe
CPU: AMD Phenom II x4 965 BE @ 3.8Ghz
RAM: Kingston HyperX 4GB (2 x 2GB) DDR3
Video: eVGA 9800GTX+ superclocked
my temps stay in the low 30C range unless I fire up BC2. Then it'll reach 37C. I'm not worried about temps, just checking the new stuff.
