Upon trying to install ANY form of Linux (tried Ubuntu 13.04, Mint 15 Cinnamon, Fedora 18 KDE), I have a few problems:

First off, I get EXTREME lag in both of their Live CDs. It starts to completely hang for minutes at a time, and then eventually the screen goes black and never displays anything again.

Here are my specs:

ASUS P8P67 Pro Rev 3.1 Motherboard (Latest BIOS 8/6/2013)
Intel i7 2600K Processor
128GB OCZ SOLID3 SSD (Latest FW 8/6/2013)
1TB Seagate Barracuda 7200RPM HDD
NVIDIA GeForce GTX 580
Yamakasi Catleap Q270 (2560x1440 @ 60Hz) via Dual-Link DVI

Secondly: I've been able to get the Operating System installed (somehow, one of Ubuntu's liveCD options as well as Fedora KDE I can make it through without lag) but then when I do install, I have to install the nvidia driver ASAP through terminal, or I get the extreme lag again. Once I install the driver, however, I just get a black screen upon reboot.

If this question is a duplicate and I missed it, please let me know and I will be happy to remove it.

I believe the problem lies with the Graphics driver, card, or my monitor itself. My problem happens even in an installed version of Linux/Ubuntu, not just the live CD. I've tried getting the nvidia driver and following a plethora of guides on this site, but they all lead in me getting a black screen on bootup and having to Ctrl+Alt+F1 to get a terminal. If anyone has any suggestions or anything, I'd greatly apperciate it.

I'm aware of two open issues with my graphics card for Ubuntu(Nouveau) specifically: 1 and 2, but the workarounds do NOT work for me. And also, the nvidia driver is unrelated to these - installing it is actually the suggested workaround, which in fact makes my problem worse.

After weeks and weeks of messing around, I was finally able to figure out my problem! It was, in fact, the monitor.

I followed the guide here and manually edited my xorg.conf file, and now everything works perfectly!

Adding the content here just in case the forums get archived:

# This section defines the Catleap (HiRes) monitor.  
# I just left this section completely the same as in the example

# The BIGGEST issue I had, was figuring out what was on DFP-0, DFP-1 and DFP-2 (which are the dvi/hdmi outputs)
