Nice review.
Just wanted to correct one thiing, though...
You said that you got the memory on the TI 4600 running at 720 mhz. This isn't exactly 720 mhz at all. The Nvidia spec for the GF2U+ cards call for a 13.6 mhz granuality (or something like that, I don't know the techincal explanation), but the person from Entechtaiwan explained it for me. Basically, if you set the card for 720 mhz, you are really running it at 715 mhz, which is what the RAM is "spec'd" to do, at 2.8 ns. The next higher step is 729 mhz, which I am sure, you saw was giving artifacts.
Usually, the next higher step will be set if you are more than halfway there. 720 mhz should round down to 715, and 722 should round up to 729.
That's why some people say they got their card to 710-720 (715), while others say they got theirs to 730 (729).
Rivatuner has an option to set "fine" clock adjustments on a low level, but I don't know how reliable this is, or even if it's supported on a GF4.
