Is this a pre-built PC with an aftermarket vid card you threw in there? Might be a crappy mobo causing some bottlenecking.
Oh yeah, though I'm an ATI guy, the 8500GT is a solid card. Not quite up to today's standards...but...

The problem with the term lag is that it is such a general term with a general meaning.
I would highly suggest reading this article - Guides: How to Get Rid of Lag - GeForce - In addition to explaining the various forms of lag and how they affect performance, it also gives a few suggestions on dealing with it.
Well worth the read.
Good luck.
