The bottom line is that tessellation really isn’t going to matter for at least the next year. In a year, you will probably be wanting another card other than a 460/470 5850/5870, so why worry too much about it. Focussing on tessellation for the next generation ATI cards is simply detracting the conversation.
Tessellation currently sucks in comparison to Fermi but, do you really sit benching all day, or actually play games? Even if I had a Fermi card I would acknowledge that at present it’s not really an important factor, and to recommend a fermi over an ati card for value for money based on the tess factor is just daft.

By the time it really matters most would have moved on from the cards they have now.
