So to start off, does the 5770 even take advantage of 16 lanes?

My motherboard (Asus P7P55E-E Pro) supports CrossfireX for 8x/8x only. Is this bottle-necking my two 5770s?
 
Solution
Not at all. You might squeeze out another 1-2FPS on a 16x/16x bored, but 8x/8x is perfectly fine, even for an HD5850 crossfire.

Assuming, of course, we're speaking of PCI-E 2.0
