Hey folks,

Sorry to make a post like this, but I've spent a few hours looking here and elsewhere and I'm coming up empty. I'd like some advice on wether I should drop some money into my machine, and if so what the smart buy would be. I'm not interested in scrapping it and starting over, and I'm not interested in spending large amounts of cash. SC2 runs right now, I'm just wondering if there is an economical upgrade I can make to improve my experience. I'm mostly thinking a new graphics card or RAM would be affordable options that could give a good performance boost.

Current hardware:
Intel Core 2 Duo E7200 @ 2.53GHz
nVidia GeForce 9600 GSO 384mb DDR3
4gb DDR2 800 RAM
Windows 7 64 bit

Thanks for any insight you might offer.
