Thanks for answers and sorry for my bad english

 

I think the Precision will be better built and tougher, but the FX 360M is MUCH worse than the XPS's 8600 GT for gaming. So if you want to do some gaming I'd go for the XPS. If you don't care about games, I'd go for the Precision.

 

FX360M is far inferior to the risky 8600GT...
