I have a BenQ XL2420t 120Hz monitor and a Gigabyte GTX680 GPU. What DVI cable do I need to buy? I know it's probably been answered a 1000 times but I'm just confusing myself so help guys!

A link to Amazon would be appreciated.

Cheers,

Any DVI-D single or Dual link cable should fit.

Actually unless you need the extra secureness of DVI (screw in pins) then I'd consider going for DisplayPort instead as it's likely to be more useful in future (assuming your GTX 680 supports it, but most do) and leaves the DVI port open in case you want to connect other devices with more common ports (as it'll accept an HDMI connection as well).

As to which cable, I'd generally go for the cheapest possible.

If you do go for DVI then you need a dual-link DVI-D cable, single link is not sufficient for 1920x1080@120hz and would limit you to a lower refresh rate at the native resolution. Going by the TFTCentral review picture the monitor's socket is DVI-D so the combined DVI-I wouldn't work (it'll carry the right signal but won't plug in) and DVI-A is analogue only.
