its a mix of both in my opinion
the cpu gets the lion's share of the blame, but something in the game is pushing that weak point.
that said, it would have been nice for SQEX to have been more of a help in it rather than the normal "well we dont think it exists, have you trying reinstalling"

but my annoyed ranting aside, there MIGHT be a fix, me and another player with a similar build used setting the Itel extrem turning utility to chance the Core IccMax and the Long and Short Boost power maxes to the intel recommended
while he did have to reduce his cpu multiplier as well. I didnt
But we both havent had a crash since doing this almost a week ago.
