How does a 290 pair with 1440p?

I'm thinking of getting the 290, with a kraken g10 and a thick single rad along with a cheap korean 1440p monitor and OC those guys to see what would happen sometime in January. I saw the benchmarks at 1440p and it seems the card can handle it but I haven't experienced anything like that (I currently game at 720p med and 1080p low on battlefield three with my two 5770's I'm thinking it's time for a completely new upgrade and giving my current parts to a friend. Anyway is 1440p worth the jump compared to say a 1080p monitor and would I be able to handle games in the long run without shelling more for another 290? (I have plans for more 290's, water cooling the GPU's in a custom, independent loop, and two more 1440p monitors when I get the money in the future) What do you guys think? I'm talking mostly gaming by the way.

Pretty decent.

The 290 and similar performing cards are all geared towards 1440p. You should be using those cards on 1440p monitors or surround gaming before you consider them for a single 1080p monitor ;D
