I don't think you will see the rez increase anytime soon, well not unless they re-release the xbox with a hardware upgrade.
Run your rez at a few settings in a game and you'll notice the fps difference. At 1440x960 the hit is apparent in almost every game I run, 1680X1050 would really take a hit on the fps.
