Basic Gaming Build

I have not built a system in a couple of years.. so heres what I came up with tell me what you think. No OMG Go Intel moron comments please unless you can prove it can be done for basically the same price.

AMD X2-4400+ Brisbane (65nm) $115.00
Asus M2N-E motherboard (other suggestions are welcome- don't care about SLI) $99.99
A.Data 2GB DDR2-800 RAM
(might get 2 sets for 4GB- its $100 cheaper than 2x 2GB set)
Existing 250GB hard drive and DVD burner

Video Card: someone help me decide is the 640 worth it over the 320? Right now my monitor is 1280x1024 might move to a 24" 1920x1200..

Option 1) EVGA 8800GTS 320MB- $279.00

Option 2) eVGA 8800GTS 640MB $389.99


Already have an Antec P160 case and Antec Smartpower 500W PSU.

PSU Output: +3.3V@32A, +5V@35A, +12V1@17A, +12V2@19A, -12V@0.3A, +5VSB@2A

Will this PSU be okay for an 8800GTS?

Thanks for the help!

If you can afford the 640 and the monitor upgrade, then do it - esp if you play GRAW you will be thankful you did. I have the 320 it's great the 1280 and lower - I don't plan on upgrading anytime soon, and if I do it will be another CRT most likely.

The SP500 should work w/o any prob - A quick trip to the psu-calc estimates your system to have +12v@19A demand at most...

Antec's specs (link) say:
* +5V, +12V1, 12V2 and +3.3V maxload: 480Watts
* +5V and +3.3V combined output: 180Watts

so the min will be +12v@25A (so it will definitely work for you no prob) and under typical loads (+5/+3.3~100w) then it is a safe bet the unit can handle +12V@30A without an issue - which is typical for a CWT built unit in that range... My TPII-480 blue is rated for +12V@33A max and anything over 30A would have me loose that warm fuzzy feeling

If you have any inclinations in moving up in monitors, I believe you have to consider the 640 unless you just want to rock the 320 until a time you upgrade both monitor and gfx card. I have a 320 (running 600/1850) and like it but even at 1600x1200 it lags on a couple games. I have it paired with a 6600 @2.925. At your current res a 320 will be great, but like I said a monitor upgrade will REALLY take its toll on that card.

If you do upgrade your monitor, then it might be wise to get the 640 version 8800 also. The extra memory will help with those higher resolutions. If not, and you decide to keep gaming at 1280x1024, the 320 version will be fine.
