Ok so i got a £500 budget, so far my build idea is as follows:

CPU: AMD FX-6300 3.5GHz 6-Core Processor (£88.79 @ Aria PC)
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler (£23.62 @ Scan.co.uk)
Motherboard: Asus M5A99FX PRO R2.0 ATX AM3+ Motherboard (£104.99 @ Amazon UK)
Memory: PNY XLR8 8GB (2 x 4GB) DDR3-1600 Memory (£38.06 @ Amazon UK)
Storage: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive (£47.94 @ CCL Computers)
Video Card: EVGA GeForce GTX 650 1GB Video Card (£86.30 @ Amazon UK)
Case: Cooler Master Force 500 ATX Mid Tower Case (£32.87 @ Scan.co.uk)
