I also bought the 3007WFP, for $1600 off ebay.
Unfortionately I cant run it at 2560x1600, linux and windows agree my laptop is dual link, and it seems to be a video bios issue, someone with a near identical motherboard (inspiron 9300 vs my xps gen 2) and a geforce go 6800 non-ultra is able to run 2560x1600 on his 30 inch apple, and I am stuck at 1280x800 with my gaming notebook(the higher end model) with the geforce go 7800 gtx, oh well.
here are some pictures showing windows detects as dual link:

http://www.houkouonchi.net/3007wfp/IM006424.JPGWhen the whole reason I upgraded to this monitor was for resolution, I upgraded from running 2560x1920 on a 22 inch CRT to this, this sure sucks, I talked to a dell manager and wrote up a big thing about the issues and why its not the LCD, or specific to my laptop which he said he could forward to an engineer, we shall see, it might be a crippled bios like I know some 7800 XFX cards were.
