[strike][/strike]WTF? For 300 dollars cheaper, you could build:
4930KRampage IV Black
16GB 2400 CL10 Trident X
GTX 780 Windforce OC in Sli
840 Pro 512 GB
2 x 1TB WD Caviar Blue
Storm Trooper
Seasonic 1250W 80+ Gold
LG Blu Ray Writer
Windows 8.1 Pro
This is a vastly faster, more versatile, and more robust system... Literally every single component of this system will run better on stock, OC'able components will OC much better and with way more headroom, will be more reliable and stable, will last significantly longer as games use more hyperthreading and cores and faster RAM, and that's with 300 quid left over and splashing out easily 250 extra bucks on a super overkill PSU and Blu Ray Player and shipping costs... !
The remaining money of 300-550 would probably cover a switch of components to the next gen of 5930K processors, Rampage V, DDR4 memory and sli GTX 880s before the year's out!
