Im simply fed up with my current computer... I consider myself fairly good at diagnosing hardware related issues yet my current system remains nearly unuseably unstable. It's a P4 2.6ghz 800mhzFSB blah blah... anyway... ive replaced every component execpt for the CPU and the Gigabtye 8knxp Rev 1.0 motherboard and im just sick of the thing randomly crashing and going very slow at times... ANYWAY, I'm not a gamer and the main thing I use my computer for is Catia. What systems are you CAD guys out there running at work etc??? I just need something extremely fast. I currently have alot of good components so im just thinking of upgrading the mobo/processor.. what do you guys think??
