GTX 470 works very well after a bit of "user input"....

First of all, the basic Nouveau drivers detected the card but hardly worked. The startx GUI ran at fullscreen quite smoothly, BUT it didn't utilise it at all for anything more than to run the monitor in full resolution.. No nice graphical options or wobbly windows or anything cool....

I had to disable Nouveau and install the downloaded x64 Linux Nvidia driver (from Nvidia.com)..

Boot into recovery mode and select the last option in the list... Disable Nouveau, then run the nvidia_________.run from there too.... Reboot, start as normal.. Then enjoy snow and wobbly windows and other cool effects

(P.s. Only been using Linux for 3 days.. So appologies For the lack of jargon... Although in all fairness, I'm a master at copy/paste-fu and "not reinventing the wheel" now :P ...)
(P.P.s. Havent added any definite commands or actions because
--a/ I'm new, and I didn't trust copying code etc from people with 1 post....
--b/ I don't get blamed for anything )
