System Upgrade Advice

[dmmontal]

I've had my current machine for about 2 years - I am still quite happy with it in general, though I am looking to improve my performance gaming-wise. I feel like I may be in a bottleneck situation here, though I'm not really experienced enough to know if that's true or not. I regularly perform thorough maintenance and have really not come across any issues that may be slowing my performance. Below are my specs - if there's any pertinent info I'm missing please let me know. Would appreciate any suggestions you might have!

Dell XPS 710
Windows Vista Home Premium Service Pack 2 (32-bit)

Intel Core2 Duo processor E6420 (2.13GHz,1066FSB) w/DualCore Technology and 4MB cache

256 MB NVIDIA GeForce 8600 GTS

4GB DDR2 SDRAM at 667MHz

750-watt Power Supply

I would upgrade the CPU and GPU. You're not going to see much performance out of an 8600GTS, but any upgrade would create a CPU bottleneck. 2.13GHz is kinda slow to begin with anyway, you would probably want to upgrade the CPU anyway.
