Will be ordering my new system on weds/thursday so just wanted to post what I'm planning on buying so that some much more intelligent people than myself can check that everything is going to be compatible 
I don't need an OS, keyboard or mouse hence why I haven't included them in my build, could go up to £1300 if it is a worthy cause,
This is what I have come up with so far,
GPU: MSI GeForce GTX 570 OC Twin FrozR III Power Edition 1280MB GDDR5 PCI-Express Graphics Card **Supplied with FREE Batman: Arkham City PC game**
CPU: Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor - Retail with FREE TrackMania 2 Canyon PC Game
MOBO: Asrock Z68 Extreme4 Gen3 Intel Z68 (Socket 1155) DDR3 Motherboard
RAM: Corsair Vengeance Arctic White 8GB (2x4GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit
PSU: OCZ Z-Series 850W '80 Plus Gold' Modular Power Supply
Case: Corsair Obsidian 650D Gaming Midi Tower - Black
SSD: Crucial RealSSD M4 64GB 2.5" SATA 6Gb/s Solid State Hard Drive
CPU Cooler: Corsair Hydro H60 High Performance Liquid CPU Cooler (Socket LGA1366/1155/1156/775/AM2/AM3)
Optical Drive: Samsung SH-S222AL/RSMS 22x DVD±RW SATA Lightscribe ReWriter (Beige/Black/Silver) - Retail
Monitor: Dell Ultrasharp U2211H 21.5" Widescreen LCD Monitor - Midnight Grey
Total: £1,239.80
Thanks for taking the time to have a read through and I appreciate any words of advice, tweaks and reassurances that this should all play nicely together
