GeForce 7800 GTX ***NOT*** dissipating 200W!
According to the Anandtech article, the new 7800 GTX is actually dissipating 9-11W LESS than a 6800U! Well, this is good news, although I'm not sure if they meant a 256MB or 512MB for the 6800U...
So all the hype about the new nVidia cards dissipating over 200W was BS. I thought they would require 120-150W, but it seems the 7800 GTX is lower volted than I expected, otherwise I don't see how could it dissipate less than a 6800U (assuming Anandtech was correct in their measurement).
Update: in the mean time, THG posted their own article, and the power consumption for the 7800 GTX was again listed as less than for the 6800U, but by a smaller margin.

Good news. I'm also interested to see how ATi's R520 does, as their cards typically draw less power than nVidia's.
I'm really kind of waiting for nVidia and ATi to release and iron out their 90nm/110nm processes. I'd really like to see a mid-range card with good performance, a low-price, and ~30w power consumption under load. Maybe this is just wishful thinking. The 6600GT has the first two, but power consumption is higher than I would've expected from a 110nm process. And unfortunately none of ATi's mid-range solutions (X700 series) can put up descent numbers, or at least nothing comparable to other cards in it's price range from nVidia. Bummer.

From TechReport's review:
Perhaps it's quiet enough even with the stock fan if you have high ambient noise in your environment, a dampened case, or just aren't very picky. (Yes, that's probably a stretch.)
I have also seen some numbers suggesting it's no louder at full load than 6800 Ultra at idle.Subjectively, the 7800 GTX is quieter than both the GeForce 6800 Ultra and the Radeon X850 XT PE, without question.

I had read that and thought that any noise improvement in stock cooling solutions is a good thing.EasyRaider wrote:From TechReport's review:I have also seen some numbers suggesting it's no louder at full load than 6800 Ultra at idle.Subjectively, the 7800 GTX is quieter than both the GeForce 6800 Ultra and the Radeon X850 XT PE, without question.

Anyway, there is another possibility. It could be quiet enough if you're hard of hearing.
While system reading and not too accurate, that gives a rough indicator.
The new stock cooling system does not take a PCI/PCI-E slot space, so it's even thinner (both the fan and the fin structure) than before.
I doubt its that much more silent.
At idle it may be less noisy than 6800U (which was horrible, if anyone still remembers):
"Following one from the power draw and core temperature trends the noise generated within the system is also less with the 7800 GTX than the 6800 Ultra, and with a greater variability between idle and load situations allowing it to run much quieter when there isn't too much 3D processing required." - Beyond3D 7800GTX review.
Also, if you look at core temps:
It'll definitely need swapped cooling to get anywhere near SPCR quiet standards.

Okay, everyone; by the end of next week, I should be able to give you guys some Power Angel readings from a machine with dual 7800GTX in SLI with a San Diego, a Raptor, an SP1614N, a gig of RAM on an ABIT SLI board and an S12-600.
I decided to skip on the TRD supercharger for my car, and dump some loot on my gaming rig instead. In the end, I actually spend less than I had budgeted for the next few months, and I'll finally be able to run pretty much any game I want at max detail, res, aniso and antialiasing.
Plus, I figured you guys would like to know what the truly extreme end of the power draw measuring stick should reach. I just put in my orders today at NewEgg, ChiefValue and ZipZoomFly (I was able save about $20 by buying across all three stores instead of just from NewEgg; ChiefValue is the same company anyway, but their prices can very a lot between the two; the RAM I got cost nearly $30 more at ChiefValue than at NewEgg!).
Looks like I'll be paying off my charge cards for the rest of this year.

Who said anything about, "quietly?"
I don't think I can water cool this very well in the P180; it's not particularly easy to mod with its incredible thick steel and the spacing is not quite right to really properly fit or mount a 120mm radiator without modding. I highly doubt any passive water solutions can handle this much heat on their own, too.
I'll think of something...

@Edward Ng: first of all, I'm red with envy (or is it green?).
May I suggest to get 2 GB of RAM instead of one? It seems that newer games, like BF2, may benefit from 2GB, especially if you want to run at maximum detail, which is the case. With 1GB you might find yourself limited, not able to unleash the full power of the 7800GTX in SLI.
The problem with 2GB is that with 4x512 you'll have to run at 2T, or get 2x1024 to run at 1T. Corsair have a 2x1024 CAS2 for a reasonable price, but I'm not sure how compatible is with the Abit mobo. If you'll want to overclock the Sandy from say 2.2 to 2.64 (at stock voltage or just a small increase), you can do it from the 'FSB' and keep the memory at DDR400 (in case your memory won't overclock well).

I'm going to use two 512s for now and squeeze the most perf I can out of them until I start hitting games that are happier with over a gig; I'd rather get better perf in most of my games and sacrifice one than speed up one and lose perf in all the others.
Oh I'm definitely not settling for stock voltage on that CPU; 2.8 is my minimum goal and I know that's not happening at stock voltage.

hmm, Ive heard that C'n'Q wont work with 3 or more modules. Is that correct? Adding 2 more 512s later would take away the C'n'Q functionality.Edward Ng wrote:I'm going to use two 512s for now and squeeze the most perf I can out of them until I start hitting games that are happier with over a gig; I'd rather get better perf in most of my games and sacrifice one than speed up one and lose perf in all the others.
Doesn't that affect socket 754 CPUs only? I thought that is because there is only support in the built in memory controller for two sticks (4 banks?) of DIMM.dexton wrote:hmm, Ive heard that C'n'Q wont work with 3 or more modules.

Found it. Here's the article. One of SPCR's too
