"Also how good is the thinkpad X60? Can it play a good quality 720p movie
without stuttering and such."
definitely
" What about the high temperatures issue?"
I personally don’t have this problem i imagine its due to some x60
collecting dust over time but you can always clean them out
"And also the overly high use of the CPU. How good is it?"

play games like for example hedgehog wars or teeworlds or mintest or
openarena its a good machine
