Hey. If you want to spend $1500, you can get a pretty killer system that could last you for the next 3 years. Check it out.

Wait, do you already have a monitor and OS or is that included in the $1500?
If so, maybe something like this would be better
CPU: Core i5 760 ($208)
MOBO: GIGABYTE GA-P55A-UD4P LGA 1156 ($184)

If you don't need it right away, you could wait for black friday and see what deals come out of that.
Both of those are pretty solid builds, though.
