Incidentally - and I realise this is in the Dell forum
- I tried various versions of the XG drivers on my Arima W830-DA (same machine as the AW m9700) - the 84.xx series drivers worked well, giving the best scores in benchmarks.. Sadly TV-Out was corrupted using Dual View mode
91.31 worked fine, but dropped my scores back a little vs. the 84.xx series drivers
91.37 don't work at all with SLi enabled - first time you run 3DMark is fine, but the second time leads to a corrupt display and a spontaneous reboot or hard lock..
All of that was at stock clocks, btw, dual 7900GS in SLi.
I've no idea if the drivers are even intended to function in SLi systems - but I thought I'd share the results in the spirit of.. well, sharing
