Hello,
 Just my 2cents. I upgrade my system awhile back and a salesman talked me into the Phenom x3 8600 CPU.  Mistake! A lot of software doesn't like the triple core. Poser is okay with it but Vue6 and Vue 7 would crash constantly. For about $40 or so more, you could get a good AMD quad core CPU. I got an AMD quad core Phenom II X4 940 3.0gHz from NewEgg for about $200 and it runs like a champ.

 Anyways, like I said, just my opinion.

No good deed goes unpunished ...
