I just got the "ultra" version of this card, and it seems fine.

Not sure about the "non-ultra".

There are a few VERY small issues with redraw of the viewports when you "maximize" the viewport.
(workaround: just deselect, then reselect anything)

I made a small mel that does this for me so it is no longer a hassle for me.

Other than that, it ROCKS

Pretty cheap too, as I picked mine up from newegg.com "Saturday night" for $123.00.

However that sale is over now, and it is back to $191.00
