Default [Solved] Upgraded to GTX580 but can only get low resolution

Hi all. I've had a GTX260 working in a 1920x1200 x2 twinview setup for a couple of years. I decided to upgrade to a GTX580. I assumed just replacing the card would be all the configuration I needed. Seems I was wrong.

Now when using the binary nvidia driver, the highest resolution I can get is 640x480 and only on one screen. nvidia-settings refuses to acknowledge the other monitor and won't let me set the resolution any higher, despite me previously having set modes for the monitors.

I'm almost at my wits' end. Any ideas as to what I can do to get this working as it was before?

Driver version: 270.18 (from the Ubuntu x-swat PPA)

And my xorg.conf:
