Hey all
I want to build my own pc but would like any tips so I can achieve high end gaming and rendering capabilities.

just follow games system requirements and you will be fine 
for exemple:
L.A. NOIRE
Recommended system requirements
OS: Windows 7 64-bit
CPU: Intel Quad Core 3.2 GHz / AMD Quad Core 3.2 GHz

How much are you willing to spend?
Do you need a monitor, keyboard, and mouse as well?
Upgrade all the parts in highest possible specs you want. But be sure that all of the parts are compatible. And be sure also that all parts are original or branded so that it will be more durable.
