Hexus has posted an all-BFG GeForce 7-series roundup. Low-, mid- & high-range are all represented, & they run each card solo and in SLi.

"BFG are staid factory overclockers with the majority of their gamer-led products, bumping things up above stock as a way to appeal. Taking a good look at their versions of GeForce 7600 GT, 7900 GT and 7900 GTX was therefore always going to be interesting."
