The Dell 3007WFP doesn't even accept a "VGA" input as it has no such connector to begin with ^^

It only has a dual-link DVI-D which requires a digital signal (it's not DVI-I as you can see it lacks the analog pins/holes to the right)...
I guess you're using the term "VGA" meaning "graphics card"... VGA is generally used to refer to the old analog RGB output... for that monitor you need dual-link DVI - which most modern graphics cards provide at "no extra cost" - just make sure it has dual-link dvi and supports the resolution needed and go for it - as you're not into 3D any cheap card with those two criteria will do fine.
