I like this!
Idk much about REALLY good current processors like the core iX but if you're considering an upgrade look into not super up to date AMD but current-ish....
I'm overclocking my Athlon2 x4 630 to 3.2 GHz pretty DAMN stable, designing 3D parts in a very heavy Pro Engineer program, on internet, handling multiple excel/word files and playing music. I never get any hang ups and I cant see the typical PC used demanding much more out of a PC than me. Its a very cheap processor too...
I also got 4G memory (now seems low) and Nvidia GeForce GTS 250 which hangles 3D animations like cake in ProE and SolidWorks and plays all my computer games and BluRays weeeee!
Total build cost was like $600 newegg build!
