My build, in process, comment plz

well,

my Plan is a budget gaming pc, I really only play limited games, I think I do want to be sure I can play Diablo 3, Heroes of Might and Magic 6.

There is no system requirements for these two yet. But i doubt they will be extremely high.

Here is my build:

AMD Athlon II x4 640
HIS Radeon HD 5770
MSI 790X-G45
320G Seaget Barracuda 7200.12 (UPS dropped my package over my 6ft fence!)
Rendition 4G (2x2G) DDR3 10600

I will buy a cheap case, I will be using my friend's spare 500W PSU for now, may be getting a better one later.

I eventually want to go eyefinity, but will have to hunt down some monitors from craigslist first... I'm thinking 3x19" 1280x1024 Dell display.


I already have HDD, 5770 and Memory, plan to buy CPU/motherboard/case on Friday.

Did I miss anything?
