Yes it's a Quadcore CPU @ 2.66 GHz. I had four sticks of OCZ memory, but they got changed to two sticks of G-Skill memory @ 1066MHz. There was a setting in some .ini file regarding multi-core processors, i changed the value to don't-remember-what but it made no difference.

The power supply is a 600W Zalman, ought to be good quality and powerful enough for even SLI setups, which i don't have.

Other games; S.T.A.L.K.E.R, Neverwinter Nights 2, Gothic 3, Oblivion, Dark Messiah and a handful of others that i've played since i built this computer. I don't have a single problem with any one of them (except game-specific bugs of course, like Oblivion's infamous CTD's), yet Titan Quest does this.

Other than the freezes, TQ runs flawlessly. High fps, no rubberbanding or any other graphical glitches.

I appreciate the help, doesn't seem to be a simple issue to solve. Might have to give up the game, just yesterday i lost an entire character. I've never managed to beat the game because of these.

+ edit: Although i have no real knowledge about how multi-core CPU's work, i somehow can't imagine it would be 700MHz each core. Most games don't know how to take advantage of multiple core technology, which means i'd be running most of my games on one or two ~700MHz CPU's. That can't be right... could it be 2.66GHz each core? Experts correct me.
