Lastly SKYMTL, is there a $150 PSU that you'd recommend for running this card? I had originally picked out the 750W PC P&C, but I'm not even sure if that's got an 8 pin GPU connector.......
So far I'm leaning towards the Corsair 750W unit.... what do you think?

HardOCP and JonnyGuru both had good things to say about Corsair's 750TX, I know (And our forum sale price is good, albeit partly MIR). PCP&C's 750 Silencer has two 6-pin and two 8-pin connectors. The thing's certified for running dual 2900XT's, after all.

Corsair's 620HX would definitely do the trick as well, as long as 120mm fan design will work in your case.

Well, I just put mine in last night (Asus flavour) as Infonec has them on sale for $449.

It performs great and I get in the same range or slightly lower FPS in COD4 with AAx2 on that I did with the 8800GTX with no AA on all high 1920x1200

When I turn AA off it goes nuts.

BUT (there's always a but )

The damn thing is like a stove element.

I was playing for about 40 minutes and it crashed. I touched the metal backplate and it's hot as hell. I have great airflow in my case and I even tried it with a 120mm Scythe Ultra Kaze pointing at the backplate and it still crashed again after the same amount of time.

I used driver cleaner to get rid of all references to nVidia this morning... so I'm going to try it again.

Another strange thing is, it scores higher in 3DMark on stock than it does with a mild OC.

I'll update you later on today as to how it goes.

Another thing to try would be to load up riva tuner and adjust your fan speed up a bit. I've found that recent cards often have problems WRT ramping up fan speed... My guess is that the GPU temps don't get into a range that requires better cooling, but the VRMs or Memory do.

The build is going to be with a Cooler Master Cosmos 1000.

The problem I see with the PC P&C 750s is that there appear to be 2 or 3 different models. I had a quick look and there are even two which are listed as Silencers, but one is crossfire certified and it appears to be quite a bit more expensive for the inclusion of the 8 pin GPU plugs.

I'm still leaning towards the Corsair, but it won't be the deal from this site as the MIR is only good until the 18'th.... :(

Yeah... I set fan speed to 100% last night, but no luck

That's a bummer!!!!! :(

As much as I hate to say it (shades of the sapphire website......) I wonder if your PSU is the culprit....

SKYMTL made a post over at NCIX about some testing he's doing WRT what kind of heat is produced by components (I don't remember if it was motherboard or vid card components) when they are hooked up to a PSU that's putting out dirty power (overworked) vice one who's power is clean going to the component.

Did you grab a GFX card stress program to check it out?

The cable lengths, number of connectors and types of connectors on all three are identical. As well as the amount of amperage available on each rail.
Purely cosmetic between the three different versions, it would seem. I'm not sure why there would be any significant difference in price. Maybe a few bucks difference at most?

$40 difference.

Again... it looks like they only ship with 6 pin GFX connectors (from the cables shown in the pics of the first one).

But then again... the spec sheet lists 2X8 + 2X6 so I suppose I'll have to verify.

I'd guess NCIX's specs and pics are outdated. Manufacturer's website states that it comes with 2 6-pin and 2 8-pin connectors (6+2 configuration), and since the 2900XT first came out, I've never seen a review of the PSU that didn't show it coming with a pair of 8 pins. But yeah, funny about the price difference, especially on something isn't even visible in most cases.

LOL at the Sapphire website reference

The PSU? Think so? 650W?

I am going to pick up a Thermaltake Toughpower 1000W soon, so maybe that will help.

But I figured this would be enough to run one of these beasts.

What are good GFX card stress programs for Vista x64?
