Yeah I did get the pro M.
I ended up just using my old D14 so that's working fine. all good :D Funny thing was, though, on the day my PSU fucking fried, so I had to rush to the PC store and buy a new PSU. Also ended up getting a Gigabyte G1 gaming instead of having to go founders so that's cool.
I prob could return the D15 but it's effort because the place is in a diff state and i'd spend money shipping back anyway so meh.
Thanks for the help. Dat 120+ FPS constant on doom on ultra Kreygasm
EDIT: to chuck a q into here, I've done the strobing 'fix' for my xl2411z including the custom res, however when I reboot I get the message that I am using the wrong DVI cable. I have to change to a non custom res, then back to make it work. Any ideas?
EDIT2: magically fixed. nevermind.
