Hey, never built my own pc, so I am looking for some advice on my chosen upgrades 
Phenom X4 955 (3.2) (does this usually come with a CPU cooler?)
Asus M4A785TD-V EVO (DDR3, PCI-2.0, AM3)
Arctic Power Supply 700w
2x1gb OCZ RAM DDR3 1333mhz
*HD 4850 1GB DDR3 or 4870/90 (the whole 5750/70 series sounds like opinion vs opinion, with the dx11 seeming to overrun every debate, however without noticing the 128bit on these cards, 4000 series can have 256bit) - Ideas?
I currently have my own CD drives, hard drive, cooler, soundcard and fairly standard n0v4tech case (not bothered with looks as of yet due to budget)
What do you think?
Any advice would be much appreciated, thanks.
