I just had to reply...
Ive been hesitant to make the switch for windoze to linux for many years now as driver support for hardware is sometimes iffy...thats the price we don't pay...

Im very new to linux
Anyway I've about had it with spending my bucks on MS software and not being able to put it on hardware where it belongs, so did this...
Quad Core Q6600 on an nvidia 680i Motherboard
2 GB SLI ready OCZ 800 MHZ RAM
2 Geforce 8600 GT 512 DDR3 cards in SLI mode.
The point is not to brad about the spec, but to illustrate that is bleeding edge...
installed opensuse 10.3...(smooth distro) to find upon reboot complete blackness...
Was I doomed to windows ? (I had indeed set up triple booting OS's {xp,vista,and linux} since I do support...and windows will always need support). Instead utilized some patience, and did some reading...
set up the repository to the nvidia driver, throttled down to runlevel three, installed the driver, and voila...still blackness...more

...poop too.
Anyway reading the logs...its seems that SaX, assigns the device in xorg.conf to the secondary card and not the primary one...a simple change from 3:0:0 to 1:0:0 has the whole thing humming smoothly along...Compiz-fusion is the hottest bleeding edge graphics engine Ive used, and this OS is as stable as any Ive ever used...
