Case - NZXT Phantom Big Tower Chassis
Motherboard - AsRock Z77 Extreme6 Motherboard
Graphics card - Palit GeForce GTX 680 4GB
RAM - Patriot Viper Xtreme 1866MHz 16GB
SSD - Crucial 512GB ( More then enough for me )

Sound card - Creative Soundblaster Recon3D

I'm looking for anything better then this, also are all the components compatible with each other ?

I'm relatively new to this, would appreciate any help at all, also please tell me if there are better parts !

Also this is for gaming mainly.

For gaming, you just need the i5-3570k, for that price you can get two 670 gtx in SLI : http://uk.pcpartpicker.com/p/DXbA
