Intel Core I7 4790 1tb 8gb 1600Mhz GTX 970 4gb Zalman Z11 Computer
Great all-round gaming PC, but as a bonus it has the nVidea GTX 970 graphics card, which gives full support for Virtual Reality.
I bought the PC custom built, on it's own, but I will throw in a keyboard and mouse, plus a WiFi adapter to get you going.
For an extra £100 I'll throw in a curved Samsung HD monitor. Let me know if you'd like that.
