I picked up a Dell 3007 WFP off Craigs list. The after market video cable I've learned is not up to the task since I'm getting garbled lines above 1280x800 resolution, which may be why I got a good deal. Looking on the Dell support forums I've learned that I need a DVI-D Dual Link cable.
My question to you all is what cable to get? On a related note, I've got an ASUS 6870 based video card currently, and following the latest system guide I'm considering a GTX670 card. I should add I've got an ASUS z68 board, 16 gigs, 2600k too. Thanks one and all for your thoughts.
