You only need a 4850 to be able to play games on high at that resolution, it will save you quite a bit.
You also linked the mobo/cpu combo to the F3. For under 700 an i5 is a tight fit, but i would swap the ram for this http://www.newegg.com/Product/Product.aspx?Item=N82E168...
its slightly more but if you are not doing the combo and drop down to a 4850 or 4870 it still comes out to less, the tighter timings will help
This psu down below will allow you to upgrade to one of those ATI 58xx cards later on...which would be a nice match with this i5 down below. For now that factory o/c gts 250 will play your games just fine on the resolution you use.
