Questions:
I was able to get a 2500k for $100, which freed up a bit of money to strengthen another component. Where would you recommend the extra $100 go? An SSD or upgrade to a 7950?
My original idea had a 1900x1200 monitor, but I had no idea how expensive those were, and how big actual monitors were. Is the jump in visual quality that big from 1080 to 1200?
