My guess is no. Today's GDDR3 chips are very, very fast (many times faster than standard memory, just like CPU cache is many times faster than standard memory). Because the very fast video memory is also closely coupled to the GPU, I'm guessing that it's good enough to act as a large cache. When the GPU runs out of "cache", it turns to the main system RAM, just as the CPU does when it runs out of L2 cache.
im sure the latest drivers from nvidia have mentioned something that they finally enabled "turbocache" for the 88xx series.....
so they might have some tehnology in place that helps with caching...Â

Turbo caching has nothing to do with on-chip cache. It's basically just a step up from integrated graphics, in which a low end GPU such as the 7300LE mostly uses system RAM as graphics memory, along with a small amount of on-board memory to boost performance over integrated solutions.
edit: just reread your post. I thought TurboCache was only for very low end cards. Maybe not, since they've got it on the 8800 series.
