Opinions on the Dell 22" SP2208wfp???

I saw this Dell monitor (well, the 20" version of it) at a dell kiosk the other day and was really impressed with it. Bright vibrant colors (blacks were especially nice), 2 ms refresh rate, nice glossy cover to the screen (glare didn't seem too bad in the mall) and has HDMI inputs.

I'm also wondering whether or not I should go with a 24" monitor versus a 22". Since the 22" will use a 1680x1050 resolution, I figure it'd be able to run some of the high end games smoother. I'm just not sure how much smoother.

I'm in the process of building a new computer with these specs Q6600, abit ip35 pro, gskill 2x2gb (800mhz) ram, seasonic s12 550 watt, evga 8800GT. Speaking of which... stupid question: the tech specs on my 8800GT only mention 1600x1024 as a resolution (it has 1280x1024 listed before, and 1920x1080 immediately after)... does that mean it won't output to 1680x1050? (Max resolution listed is 2560x1600. I haven't had a chance to install it yet.)

Thanks!
