I have had the case, and CPU for a while, other than that the PSU, SSHD, GPU, RAM, and Motherboard have all been replaced within the last year at most. The BIOS is that ASUS utility that comes with the M5A97 LE R2.0. I will be getting a new full tower this christmas as well, that has 6 fans on it instead of my current 3. FPS wise, I havent noticed any big issues, other than the very occasional Frame drop in LoL. In Payday 2 I dont notice any issues.
EDIT: I have never gotten any alerts either saying that my CPU is getting too hot either and I have had some Prolonged (4+ hour) gaming sessions in things like Far Cry 3 and Total War games
