Windows 7: ATI HD4870, PowerColor HD4870 PCS+ or ATI HD4890

The HD4870 is an exceptionally fast card. The biggest difference between that and the 4890 is the price. Get a 4870 for now, add another later. I run QuadFire and it's ridiculous overkill. I'd only run two HD4870's if I was doing another build.

Well i was looking at the 1gb 4890 because its in between the 1gb 4870 and the 2gb 4870x2. I can get a 1gb 4870 for $230au, a 1gb 4890 for $340au or a 2gb 4870x2 for $450au. I was originally going to get a 4870x2 but i'll just have to wait and see what kinda money i can round up in the next couple of months

EDIT: If i got a corsair hx850 PSU would it run 2 hd4890's in crossfire? probably a stupid question but i thought i would ask it. Or maybe 2 4870's? depends what i end up getting

Any quality 850W should handle both 4870/4890 crossfire fine. If push comes to shove, a single 4870 should keep you going for quite a while. You can save up and then grab a 4870x2 for some tri-fire

I just went to my local MSY to pick up two XFX 4890's. They didn't have any. In fact they stopped stocking XFX altogether. The only 4890 they had was a single powercolor and that was reserved

Now I have to order online, pay an extra $100 all up and fess up to my girlfriend I'm doing it (I need her credit card since I flatly refuse to have one )

*sigh*, Bloody upgrade bug

Sounds like you have a plan there "tri-fire" i like the sound of that . That sucks they didnt have the XFX 4890, that looks like one beast of a card. You have basically the entire PC i want going by your system specs, P5Q-PRO, Q9550, HX1000 haha oh well.

samstar, I would not run 2x HD4870X2's on 850w. You need 1KW to be safe. 850w will be sufficient for CrossFire, not QuadFire.

Whoops. You're right mate. I got carried away there
For tri-fire of one single 4870 + one 4870x2 you would need a 1KW+ for headroom like CZ said. Sorry about that

dont move too fast if your building upto 6 months.

amd are releasing a new line of direct x11 cards in line with the release of windows 7,if theyre too expensive im sure the older cards will take a good price drop.

"With Microsoft Windows 7 set to be released in October 2009, rumors are flying rampant in the video card industry as DirectX 11 graphics card will also be launching at the same time. As many of our readers are already aware AMD has already been pushing DirectX 11 as the next be step for graphics. Those who read Legit Reviews will remember AMD started promoting DirectX 11 all the way back to August 2008 when they discussed plans to add full support for DirectX 11 in their Stream Software Development Kit (SDK). More recently on June 2nd, 2009, AMD actually demonstrated tessellation on the worlds first DirectX 11 graphics processor! AMD says they are on track to launching their 'Evergreen' series of DirectX 11 cards around the time Microsoft Windows 7 launches, which makes sense due to all the marketing hype they are trying to build." ~legitreviews.com
