Vista - Graphic Cards: Best for less??

Here was two GPU's (graphic cards) i was looking at...
RADEON HD 4850
Phenom II

Here is the computer i'm thinking of building... methinks it needs some tweaks.
CPU: Quadcore Q8200
PSU: 650W CoolerMaster
RAM: Kingston 4G @ 800 MGz
Mainboard: I don't know at this point. I was gunna buy a cheap one that would work with the things i wanted.

I stumbled accross a site about ATI and Nvidia with the 6 & 7 series... ATI had a
Geforce 6800GT vs Nvidias Geforce 6800GS which will show that while one number is lower on one, it compensates with a higher number on something else...therefore - they're the same damn thing! And look at the price difference..

Here were the differences between the two in BOLD text.

Pixel Pipelines: 16
Core Clock: 350 MHz
RAM Clock: 1000MHz - 256MB DDR3
Price: $200

Pixel Pipelines: 12
Core Clock: 400 MHz
RAM Clock: 1000MHz - 256MB DDR3
Price: $120

Anyways since i've seen this i was wondering if any of you wonderful people out there could show me a graphic the same for cheaper or maybe a better one for cheaper etc etc..

NOTE: if you could show it in AUD as i live in Australia.

Here was another Nvidia and ATI compared to one another...

Pixel Pipelines: 16
Core Clock: 650 MHz
RAM Clock: 1500MHz - 512MB DDR3
Price: $530

Pixel Pipelines: 24
Core Clock: 650 MHz
RAM Clock: 1600MHz - 512MB DDR3
Price: $399

Which would you choose? The crummy ATI RADEON X1900XTX for $530!! or the Nvidia Gefore 7900GTX for $399?

you could probably get a gts250 for less than all of those & it would be much better.

the Phenom II is NOT a gpu it is a cpu and it outdoes the Q8200
but the 4850 is a good gpu

Yeah I got two nvidia 9800 gt's for a little over a hundred dollars each but that 4850 IS a nice card. Not sure why you're looking at geforce 6 and 7 series cards.

I wasn't looking at the 6 & 7 series to buy. I was using it as an example.

Oh lol! i looked it up on google lastnight and thought i swear it had graphic cards up. Plus it was also 2am in the morning and i do full time TAFE (Like college).

MSY can be pretty cheap. It depends on whether your close to a store though:

MSY-The Name you can trust-More than 10 years in IT industry-Nationalwide branches serve you & always offer the best up today IT price

The 4850 is a good bang for buck card. I'm thinking about grabbing another for one for crossfire to tide me over until the high-end cards come down a lot with their high end prices.

EDIT:

Thought about it, crossfire and x64 is still flaky at best and more trouble than it's worth

why not go ahead and get a 4870? then when crossfire is better crossfire them in the meantime use the 4870

Decided to get a ASUS GF 9800GT because it's almost the same as the RADEON 4850. I dont have the money to get a 4870 and whats that little bit more gunna do for me anyways. i don't wanna spend $500 when i can spend $200...
