NVIDIA's GeForce 8800 (G80): GPUs Re-architected for DirectX 10

The Test
In our game tests, in every game we enabled the highest level of quality possible as far as features and effects are concerned. Where it was an option we enabled 16xAF in game. In games with "texture filtering" settings (like Battlefield 2) we endabled the highest level of filtering in game. In Oblivion we forced 16xAF in the control panel.
With the exception of Oblivion, we enabled AA in all our general performance tests. Where we were given the option, we chose 4xAA. In Black & White 2 and Company of Heroes we enabled AA in game (High for BW2 and Enabled for CoH).

A Few Words about Performance Per Watt
In the coming performance pages we will be looking at the performance of the 8800 series of graphics cards as well as power consumption and performance per watt of our test systems. Note that the power consumption and performance per watt we are reporting is for the entire system, and not just the GPU, so while you don't get an idea of the performance per watt of the GPU alone, you do get an idea of the performance per watt of the entire system configured as we have. This is an important distinction to keep in mind as performance per watt of the GPU alone could be very different than what we're reporting here. What these numbers will tell you however is the most power efficient setup we have configured here today.

If you're using Firefox, get, and install the extension "flashblock". Just did this myself today, tired of all the *animated* adds bothering me while reading articles.Sorry AT guys, but we've had this discussion before, and its realy annoying.

Do you want to be able for us to continue as a site? Because ads support us. Anyway, his problem is related to not seeing images, so your comment about blocking ads via flashblock is completely off topic.yyrkoon - Thursday, November 9, 2006 - link
Of course I want you guys to continue on as a site, just wish it were possible without annoying flashing adds in a section where I'm trying to concentrate on the article.As for the off topic part, yeah, my bad, I mis-read the full post (bad habit). Feel free to edit or remove that post of mine :)

What browser are you using?falc0ne - Thursday, November 9, 2006 - link
firefox 2.0JarredWalton - Thursday, November 9, 2006 - link
If Firefox, I know there's an option to block images not on the originating website. In this case, images come from image.anandtech.com while the article is on www.anandtech.com, so that my be the cause of your problems. IE7 and other browsers might have something similar, though I haven't ever looked. Other than that, perhaps some firewall or ad blocking software is to blame - it might be getting false positives?archcommus - Thursday, November 9, 2006 - link
Wow to Anandtech - another amazing, incredibly in-depth article. It is so obvious this site is run by dedicated professionals who have degrees in these fields versus most other review sites where the authors just take pictures of the product and run some benches. Articles like this keep the AT reader base very very strong.Also wow to the G80, obviously an amazing card. My question, is 450W the PSU requirement for the GTX only or for both the GTX and GTS? I ask because I currently have a 400W PSU and am wondering if it will be sufficient for next-gen DX10 class hardware, and I know I would not be buying the highest model card. I also only have one HDD and one optical drive in my system.
Yet another wow goes out to the R&D monetary investment - $475 million! It's amazing that that amount is even acceptable to nVidia, I can't believe the sales of such a high end, enthusiast-targeted card are great enough to warrant that.

Sales of the lower end parts which will be based off G80 are what make it worthwhile, I would guess. As for PSU, I think that 450W is for the GTX, and more is probably a safe bet (550W would be in line with a high-end system these days, although 400W ought to suffice if it's a good quality 400W). You can see that the GTX tops out at just under 300W average system power draw with an X6800, so if you use an E6600 and don't overclock, a decent 400W ought to work. The GTX tops out around 260W average with the X6800, so theoretically even a decent 350W will work fine. Just remember to upgrade the PSU if you ever add other components.photoguy99 - Thursday, November 9, 2006 - link
I just wanted to second that thought -AT articles have incredible quality and depth at this point - you guys are doing great work.
It's actually getting embarrasing for some of your competing sites, I browsed the Tom's article and it had so much fluff and retread I had to stop.
Please don't forget the effort is noticed and appreciated.

It wasnt mentioned in the review, but whats the purpose of the 2nd sli connector?
