Gigabyte H77M D3H or MSI ZH77A G43 or Asrock H77 Pro4/MPV
Which of the above boards are best for the following config:
Intel i5 3550
Sapphire HD 7970 OC
Western Digital Caviar Black 1Tb
Kingston HyperX 1600Mhz 2 x 4Gb
Corsair Tx 650 V2
The motherboard you have chosen allows you to overclock.
Your config looks good but i would like a GTX 660 in there
also ssd does not improve gaming performance.
It just help in loading games faster.
