And, ummm, even if the 5770 did magically double usable bandwidth you're looking at two 128-bit controllers using slower memory.

So, yeah, guess I'll just ignore that thing you said earlier about tesselation in 6xxx
where did you get twice the triangle setup ?

one 5770 a stock is 13.6 gigapixel one 5870 at stock 27.2 Two 5770 are equal to one 5870.

The tessellation unit is the only advantage their.

A smaller memory bus isn't necessarily slower, because it's usually shorter then a bigger one.
