*Everything copy and pasted from Newegg (so hopefully they're easier to find) since I can't post links yet.

As you can probably tell by the age of the parts it's been a few years since I've built a PC, but my current plan was to buy 8GB of 1600 Memory to replace my 4GB (figured it might be easier to just replace it rather than mix with newer memory?), at least upgrade the graphics card to a EVGA GTX 750 Ti (or perhaps I should just splurge and get a 970?) and then upgrade my MOBO and CPU in the future unless it is horribly bottlenecking the system. Perhaps I could try overclocking to give the CPU a bit more longevity?

Thanks guys

There we go; and after-market cooler for overclocking, a high-end graphics card (although you might want to wait for the GTX960 that'#s to be revealed later this month) and 8GB of RAM.

Thanks for the recommendations, especially the video card, it looks like a great deal.
