Which DVI cable is best for me?

I'm building my own machine and I'm looking for an appropriate DVI cable for my GPU to Monitor connection. The monitor I'm getting is a Dell 2405fpw (2407 if it comes out in the next two weeks). I will be using two eVGA 7800GTX KO 256mb GPUs in SLI configuration and I plan on gaming at 1920X1200 resolution. I'm aware that the DVI cable included with the monitor is not dual link and that I will need dual link to get the performance I am looking for. I don't know a lot about DVI cable brands or what to look for and I'm hoping someone out there can point me in the right direction. Thanks in advance!
