OK, so if Kubuntu comes up and runs stable for an hour or two then I don't think it's your new rig or monitor.

I have a suspicion that Kubuntu booted and loaded the Open Source driver and not the nvidia driver, but that's just a guess. However, if that's the case then you can almost certainly use whatever Kubuntu has used as far as drivers and an xorg.conf file and see if that helps with your Gentoo issues. Once you get Gentoo working with the Open Source driver then you could investigate using nvidia's.

If you have time to let the machine soak awhile then I'd consider a reboot into Kubuntu and then take a look at what drivers are loaded using lsmod. There will likely be a huge list. I have a 2 year old machine that's not unlike your new machine (yours is slightly more powerful I think) but the list of drivers loaded is just huge. However it works, and once you get it going with lots of drivers you can then rebuild things with them in the kernel if you want to.

Anyway, look at lsmod and report back. Here's mine running Kubuntu, and I have no xorg.conf but it runs fine with 3 monitors.
