https://bbs.archlinux.org/viewtopic.php?id=162768 is the main point of discussion for it - too much to read through entirely, but the top posts include a lot of info, and it contains a lot of valuable information on quirks for specific hardware if you search. Some of the stuff is outdated though (eg the kernel includes a lot of the patches now), and it's targetted at Arch, but most instructions should apply to any distro.
Another key point is, you need VT-d/IOMMU support on your motherboard and CPU, which isn't universal (only in the last few generations of intel CPUs, with some excptions that don't support it. And motherboard support can vary between OEMs). Check https://docs.google.com/spreadsheet/ccc?key=0Aryg5nO-kBebdFo... to see if others have had any luck with your hardware, or before making any purchases.
https://www.reddit.com/r/linux_gaming/comments/2z2y7h/gpu_pa... is another fairly concise guide (a little out of date though).
