Thanks guys.

 I actually replaced the stock heatsink with: http://www.pricecanada.com/p.php/Coolermaster-Hyper-212-Plus-Direct-Touch-RRB10212PGP-620782/

 So I don't think heat is the problem. I will definitely tweak my Windows 7 and turn off all unneeded services.

 I have Windows 7 64 bit and Poser Pro 2010 64 bit.

 I think I'll give overclocking a try. 3.6 with turbo boost off so it's constant. I'm pretty sure my CPU at 2.66 is the bottleneck right now.
