Little Endian said:The 6800GT is a much better value than the 6800 Ultra. The $599 6800Ultra costs 20% more than the 6800 GT at only $499 however the 6800 Ultra is generally much less than 10% faster in most cases but demands a 20% higher premium.

Read the article and think about the benchmarks in some cases the 6800Ultra is no faster than the 6800GT and when it is it only beats the 6800GT by usually 3-5 Frames per second. Actually if you average the Performance gain that the Ultra has over the GT it really is only about
5-8% which litterally translates to a less than 5 FPS difference which is unoticable in the grand scheme of things.
Wrong, the Ultra is ALWAYS faster than the GT. And it is not usually by 3-5 frames. The only time a GT is close to an Ultra is when a factory OC'd GT is compared to an Ultra at reference speed. The GT is still more popular because most can be OC'd to Ultra speeds. More and more Ultras are coming factory OC'd though. Most GT's can easily reach these speeds and more, but under normal circumstances only the Ultra's can hit Ultra Extreme speeds. I've come close to hitting UE speeds, 440/1100, with water on the core, but without water on the mem i'll never hit 1200. It's not impossible but not easy and i see no reason to voltmod since it wouln't really make a big difference. See my sig
The 6800 Ultra 's MSRP is $499.99. When i bought my GT i held an Ultra in my hands. Little did i know that would be the last time i would see one in retail.
You think 599 is bad? I've seen a pci express 6800 Ultra go for "only" 679 at GameVE... and peeps are dying to build SLI systems.
Less than 5 frames performance difference? Yes we can tell the difference! PC GT's don't do opengl triple buffering(don't know about mac's) and 5 frames can be the difference between running at 60fps, or dropping to 30fps.
Don't worry about getting an Ultra. For gamers that are adventurous and don't care about dual dvi, just overclock your GT. With the G5's awesome case cooling you should be able to hit 425/1100 easy.
