2900XT vs 8800GTS 640mb

Im going to buy a new graphics card, either a 8800GTS 640MB or a 2900XT. my resolution is 1600x1200.

The rest of my specs are:

GA k8NXP SLI

AMx2 3800+

2GB RAM

Creative audigy 4

430 watt power supply

Well, Thermaltake.. so you have that crappy TR2 430W model with a single 12V+ rail with 18 amps. :(

I'd go with the HD2900XT and a decent power supply.

or

these are the local places that I would be most likely to buy from

This Antec NeoHE 500W would be a good choice.

Dude, I'm from AUS too! :D

Go for the HD 2900 XT and a Seasonic S12 550w PSU:

yeah, i went with the intention of buying a 2900XT but ended up with a full system overhaul -

2900XT, Q6600, 2GB ram, Asus PK5 and a coolmaster 600 watt PSU

It should last me for a while.
