Excellent choice in psu, gpu (i have the same) & screen resolution (same as well). No black bars in HD playback.
If you can't wait for a new pc, the barebone is a good choice. If you can wait, wait for P67 to be restocked. The SB CPUs are not affected at all. In fact, I'm running 2500K, P67 & 8 gigs ddr3. Default frequency is 1333mhz or 667mhz to be exact.
Nope, I can't recommend a better build with that budget. Not at this time.
