Need help on Nvidia Ultra 6800

I have a few questions regarding this card, for those who owned it, please help:

1) Which OEM makes the best cooling solution? so far, every OEM I visited shows something different:

Asus:

http://usa.asus.com/products/vga/v9999ultra/overview.htm

BFG:

http://www.bfgtech.com/6800U.html#zero

what is a water block?

Chaintech:

http://www.chaintechusa.com/tw/eng/product_spec.asp?MPSNo=14&PISNo=295

eVGA:

Gigabytes

http://www.giga-byte.com/VGA/Products/Products_GV-N68U256D.htm

Leadtek

MSI:

http://www.msicomputer.com/product/p_spec.asp?model=NX6800_Ultra-T2D256&class=vga

PNY:

http://www.pny.com/products/verto/geForce6/6800ultra.asp

XFX

http://www.xfxforce.com/product_view.php?sku=PVT40FUD

Last but not least, this is the most ethical vendor, they tell us the sys. requirement

but it seems their cooling design are different, so how do you know who's the best?

2) I don't understand why all these fuzzies about Ultra 6800. Does the Ultra 6800 supports 2560 x 1600? Or is it really 2048 x 1536? If it only support up to 2048x1536, then which Nvidia do I have to go with to get "Dual Link DVI signal" and 2560x1600 x 67 million color? But on the other hand, Ultra 6800 is the latest product, it should have latest tech. that supports 2560x1600x 67million color, should it not?

3) Why are you guys so much into this one when it is only AGP 8X, it seems to support PCI express, but 6800 ultra is not a PCI Express x16 technology, and yet it is the latest card, so I don't get it. IF it is the latest, it show comes w/ PCI express connection like those new ATI cards.
 
Well, I'll answer one question for you :D

3. Despite the soon-to-be-antiquated AGP 8x interface, the latest generation of nVidia cards have proven to outperform their previous models. Besides, AGP is going to be around for a while. The pipelines have double from 8 on the nVidia 5950u to 16 on the nVidia 6800u, which makes for a faster, more realistic "cinematic" gaming experience. The implementation of Shader Model 3.0 promises better graphics as well. It's features like this that have us all excited :D (Well, that and we are all dorks who want the latest and greatest...)
 
dont think to hard about any of this, their wont be any big differnce between cards makers for 4-6 months minimum,

otherwise whichever company uses a decent copper cooler will automatically be better then all the other coolers. leadtek for instance

just from your last few statemetns i see you are comparing numbers, but probably not somethign you will ever use. do you actually game at 2048x1536? lots of numbers are fluff numbers, the only thing that will help you sort out fluff from fact is experience and research, you need to read up lots of reveiws and over time youll start to see patterns. but dont worry this is kinda research that is sorta fun.

like:
-rev 1 of anything is buggy and is always followed up 3 months later with a fixed product
-agp4x-agp8x rarely equals more then 2% speed increase same thing with pci-e
-prescott P4 3.0ghz loses almost all gaming benchmarks to 1.8ghz athlon 64

unless your planning on overclocking hte hell out of a card. finding a good deal and adding a 15$ aftermarket cooler is a much better proposition.

Thx for the reply. But I actually need 2560x1600, not for games, but for some other purpose, but surely still play games at a lower res.

Now from the above link, can anyone tell me what is the difference between:

NVIDIA GeForce 6800 Ultra DDL from Apple

vs. the Ultra 6800 that we talk about?

Apple said that card is 2560x1600, but isn't the Ultra 6800 max out at 2048x1536?

Who can solve this mystery?

How can you call AGP " soon-to-be-antiquated "? There isnt a video card that saturates the AGP at the moment. It will be around for quite some time. Remember how long it took for ISA to disappear?
 
<i>">>Apple said that card is 2560x1600, but isn't the Ultra 6800 max out at 2048x1536?"</i>

Easy. Most cards today don't actually limit at 2048x1536 anymore -- even your old Geforce3 card or my ATI Radeon 7500 card. With PowerStrip, and some registry modifications to Windows XP, I can coax an old card to output 2400x894 or 1948x1122 or another custom computer resolution of my own choosing, AS LONG AS the "DOTCLOCK" spec is not exceeded.

You can actually make an old card do double resolution at half refresh rate -- For example, an old video card that can do 1024x768 at 60 Hz can sometimes be coaxed
to output 2048x768 at 30 Hz. (Or 1024x1536 at 30 Hz)

Today's video cards have so much headroom, like 2048x1535 at EIGHTY FIVE hertz (85 Hz) you have plenty of headroom to go to 2400x1600 at SIXTY hertz.

Mystery solved -- And if you don't believe me, search "PowerStrip" and "custom timings and resolutions" at www.avsforum.com -- "Home Theater Computer" forums -- where creation of custom resolutions is necessary learning experience for certain video cards to coax it to output true HDTV for connecting a computer to a HDTV with six times sharper graphics than S-Video (never connect S-Video or Composite to a HDTV; there's a way to get six times sharper computer graphics), as explained by many members on that Internet's most popular Home Theater Computers discussion site.

And if you're familiar with Linux Xconfigurator / XF86Config files, etc, where you can create custom computer resolutions for the Linux Desktops (X-Window - usually GNOME/KDE), you can hack for example 1344x776 or whatever custom computer resolution you want, as long as it DOES NOT EXCEED MAXIMUM DOTCLOCK SPEC.
 
What's the min. vertical freq. for a LCD monitor? Is it still 60Hz? If so, I'll need to power strip it and still yields 60Hz or higher?

Is the above risky? Would it overheat the chip?
