I've had this PC a while now, I got this for my website design and editing not only for gaming, this PC is flying through tasks my old PC would struggle with often losing data and hours of hard work.
I7 2600k @4.6mhz
Asus ROG Maximus IV mobo
8gb Corsair xms3 @1600mhz
Dual AMD 6970's
XSPC watercooling cpu+gpu
Corsair HX1000w psu
600gb WD Velociraptor
1tb Samsung spinpoint data HD
The thoughts behind some of the component choices:
1st choice of GPU would of been nVidia 580, but we took a gamble with going down the crossfire root as 2 6970's at the time of build cost the same as a single 580 and in theory would out perform a single 580, so far we have been happy with crossfire seeing nearly a doubling of fps in Crysis and BFBC2 and running stable with max settings, only NFS Shift gives us problems which does not support xf at this time.
We choose xms3 ram at 1600mhz as looking at kits upto 2000mhz showed little performance advantage in Sandybridge systems.
We choose watercooling for cool and quiet running, the fans run at a constant low rpm even underload and everything is nice, quiet and cool.
We stuck at a 4.6mhz overclock as this is nice and stable and not taxing at all for this processor on water and runs plenty fast enough for our needs.
PS this is a huge improvement over my last Best Buy PC, and anyone who thinks buying a high end PC will make them into a pro player overnight is mistaken, wether you play on a low end pc or high end your skill is what it is!!
