Here is the gaming i7 rig I'm looking to purchase asap. I want to do Crossfire or SLI, I'm not to worried about buying now, then dx11 cards coming out due to xfx's upgrade policies etc. Or should I just wait till september to see the specs on the new dx11 cards, if I don't like em, just add a second 4890 or 275?

Second question is, 4890 or 275? Right now the build price is at $1275 with just 1 4890 card in my cart. Third question, what are the chances of getting a D0 stepping from newegg?

Also I will be overclocking this to ~4ghz

My build: Feel free to critique or make changes.

1) if you don't get a DX11 card then you'll miss out on some effects and fps may be lower in games.

2) 4890

3) about 99.9%

now, most of the games I play are not fps shooters. I primarily just play gta4, wow... and soon to be aion when it comes out in september.

I think all of those are just dx10 games... so would I still be better off just doing a 4890 now, and then two 5870's later? Or for my uses, just stick with two 4890s?

^ two 5870's would blow the 4890's out of the water even in DX10/.1 games, but it's your money.

ok, I hear ya... so 1 4890 now, two 5870's later.

Anything else before I hit purchase?

Diff motherboard? Memory? etc? Or is it all solid?

maybe drop down the mobo to a P6T vanilla, as you won't need the extra features of the P6T deluxe V2.

otherwise it looks good.

no problems with the p6t running 1600mhz memory?

two GTX260 or two 4870...

Any single card config would be a waste on a i7. You can achieve the same result with AMD for less.

^ you're forgetting most people, even gamers, will have MSN, a couple of tabs open, listening to music, etc plus you've also got background apps.

and this is where the i7 shines.

ordered, I said to heck with it, and grabbed two 4890s, I can step them up to 5870s when they come out.
