How about this build?

One thing to note: Intel sandy bridge HD2000/3000 graphics support maximum resolution of 1080p. If you are getting a bigger monitor (like 2560x1600), you'll have to either get a discrete card, or move up to ivy bridge.
Also, I would not go for AMD CPUs, they are very subpar for their price. Lastly, I could not find any 160 GB ssd that was cheaper than this 240 GB.
