What to build around a GTX 280

I am planning on buying the GTX 280 when it comes out. I would like some advice, though, on what other parts would compliment it best without wasting money. I was thinking to buy the evga 790i mobo, 4gb ddr3 1333, core 2 quad q9450, and put it all into an antec 900. By the way, I already have a Thermaltake Toughpower 850w PSU. Anyone have experience/advice about these components?

if you are not going to use sli i would recomend getting an x48 motherboard with ddr2. the power supply should be enough. the gtx 280 is supposed to be very power hungry.

hmm, I have to disagree on the x48 since it doesn't offer any real improvement over the x38. Go with a nice x38 board from Gigabyte or Asus, and get a DDR2 version. You won't be able to see the performance of DDR3 until Nehalem anyway. I would go with the Q9450 for the CPU and get that thing cranked up to near 4GHz. No one can tell you exactly what you'll need until launch however :\

How power fungery are we talking about? I have a 610 watt PCP&C silencer. Should be enough?

probably, not many systems ever really use more than 450w anyway

I read that one gtx 280 would use 236 watts. If i were to add a second gtx 280, would a 850w PSU be able to handle it?

Yep

That PCP&C sounds fine for that system, you won't be able to add a second gtx unless you go with a nVidia chipset (and they do suck compared to intels..I've had at least two of each).

Monstor, I have to disagree.

My 790i allowed me to OC my Q9450 to 3.6 on all auto settings, and has been rock solid handling my 2x 8800 GTX's.

Plus, it uses about 12% less power than the intel boards (x48).

And my 4 gigs of OCZ gold DDR31600 rock right along, and the board auto took them down to 1t without any effort at all.

Unlink the fsb/mem. and raise the mem voltage to 1.9, and you are golden.

Doubtful the G will use more than 250 watts, one chart had them using the same as the 8800 GTX, around 189 watts at load.

Ok, fair. Let me reword my opinion. :p  Look at the price/performance ratio. That 790i will rape your wallet of cash (but that's probably not a problem if you're going SLi+DDR3 anyway). It can't quite reach the same clocks as an intel chipset, or the stability. I'm not too sure about the 790i, but I think that the 780i had memory corruption problems when overclocked over their rated specs (or a certain limit I don't remember). Another problem that I have with nVidia chipsets are the drivers provided for them. Now, I'm not narrow minded in this aspect as I've talked to others about the barely functional drivers (on the chipset end), sometimes even causing BSoD. I never owned anything over an nForce 570 SLi, though.

Reading around a few forums basically see the same things. From my experiences, the FSB can't be stressed as hard and the drivers have issues.

Give me a week or so, and I'll be able to tell you how far I can clock my Q9450 on a gigabyte x48 board (DDR2). Just waiting on a front case fan and antec spot cool to make sure things stay nice and cool inside my case.

Excellent, i'm waiting for that now sciggy, I'm in the same boat here in the fact that I will be SLi'ing GTX 280s, and i'm still not sure wether to go with an intel board ie Rampage, or a 790i :(
