Input on building a PC

[hoffmanxtreme]

Just sold all my old junk, now looking to build my own Tower. Im not that new to computers but I am squid to building one from scratch. Any pointers?

My thoughts:
i7 processor minimum of 1.06ghz
6GB system RAM
Dedicated graphics card(Not integrated) I think Im looking for a ATI or NVIDIA with 256mb of ram or higher?
DirectX 9 or 10 compatible graphics and sound

These are actually system requirements for the editor I want(AVID) but I dont really know much about differences between hardware parts.

Wrong forum website yes, but maybe there are some killer computer geeks on here I am unaware of ??
