Not worth getting the black edition, u can just OC the 1055t urself.
The motherboard is fantastic no problem, lots of room for the future
this looks more like a gaming comp so with the money u save from getting a 1090t u can get a 6970
the PSU i would upgrade to a quality 850 just incase u wana go crazy for future upgrades (if u didnt then u wouldnt of gotten a mobo with 5 PCie slots lol)
Final price is $1,430.47 with a 6970, or u can just get a 6870 (still a rape as card for a 23 inch monitor, and then later down the road crossfire it = hardware goodness
$1,290.47 with a Asus DC 6870 up to u for what to get... 6970 or 6870
hope this helps
