I been wondering about this, the 6770 has higher clock speeds all around, but the 6790 has more memory bus rate.
It's essentially 128 vs 256, but according to harware compare the 6770 is faster at some tasks because it has a higher texel and pixel rate - which doesn't make sense to me (why AMD did that).
6770 6790
Bandwidth 67200 MB/sec 134400 MB/sec
Texel Rate 36000 Mtexels/sec 33600 Mtexels/sec
Pixel Rate 14400 Mpixels/sec 13440 Mpixels/sec
But essentially my question stands, can the 6790 take advantage of its 256 bus or is it merely a selling point to make people choose it over a GTX 550-ti
