Here's something interesting. During our testing of the reference card with the same ForceWare 185.63 beta drivers we found the reference card to display extremely erratic frame-rates, being perfectly playable one moment and practically a slide-show the next, lowering the average frame-rate.
The retail BFG model, which is ostensibly the same card, albeit with slightly higher clocks, returns a higher average frame-rate, as the graph shows, but performance is still subject to 'near freezes' on a regular basis. NVIDIA R185 drivers - and we've tried the later R185.66s - seem to be the culprit here.
The Radeon HD 4890s still give it a good beating at every resolution, and they're tested on the very same platform, too.
