Evening all. Should hopefully be building my first ever rig this weekend, and over many moons I have gathered my desired components. I believe they all work together and are decent choices, however please have a look over it incase I have made a noobtastic mistake somewhere. 
*Intel Core i5-2500K 3.30GHz (Sandybridge) Socket LGA1155 Processor with FREE Lost Planet 2 PC Game - Retail
*Gigabyte P67A-UD3 Intel P67 Chipset (Socket 1155) DDR3 Motherboard - (Sandybridge)
*Corsair XMS3 4GB (2x2GB) DDR3 PC3-12800C9 1600MHz Dual Channel Kit (CMX4GX3M2A1600C9)
*Sapphire ATI Radeon HD 6950 2048MB GDDR5 PCI-Express Graphics Card
*Antec TruePower New Modular 650W Power Supply
*Coolermaster CM-690 II Lite Dominator Case - Black
*Samsung SpinPoint F3 1TB SATA-II 32MB Cache - OEM (HD103SJ)
*Cooler Master Hyper 212 Plus CPU Cooler (Socket AM2/AM2+/AM3/775/1155/1156/1366)
*Samsung SH-S223L 22x DVD±RW DL & RAM with LightScribe SATA Optical Drive - Retail Box Black
*Microsoft Windows 7 Home Premium 64-Bit - OEM (GFC-00599)
In regards to the mobo, I'm not bothered about CF/SLI, and I won't cry if it doesn't allow me to get a mega overclock on the CPU.
Thanks in advance.
