I haven't clocked the temperatures at all honestly, they sent me a replacement system that had the video card, ive only played world of warcraft on it so far. I've never overclocked it either, i was kind of pissed i couldn't utilize the x9000 overclocked on the m6300 so I've never bother with overclocking the computer.
I haven't really used my m6300 much at all in general
The price i am not so sure about yet. I'll keep you updated
