Fastest 2D card in the universe

Running two Samsung 23" LCDs at 2048x1152. Windows XP for now but soon to be either 64-bit Vista, Win7, some derivative of linux, or all three.

I'm not a gamer. I get in the mood once or twice a year and load some ancient game (ancient by the standards of the day) on the machine, play it for a week, and then delete it.

I want the fastest 2D speeds money can buy. Instant screen paints, etc. I want nothing occuring on my displays to be slowed down by the graphics card. I do a lot of work with Google Earth and USGS maps, GPS, etc. And the usual office stuff.

I was looking at these:

Partially because of its price after rebate, but also because it will handle 3D, if I decide to use it, for the next few years.

But I'm worried about heat. I don't want an oven inside my case.

So what's the fastest 2D card that can drive two displays at 2048x1152, that is cool (quiet, passive heatsink if possible), and yet still has meager 3D performance for a game or two every now and then?

Thanks!

Well said outlw6669. 2D doesnt' really push a card, so you'll be all set with something basic and mainstream.
