will my Graphics card be able to handle a 24" monitor?

[mannsupreme]

hello all,

i currently have a PNY Nvidia GeForce 9800GTX+ 512MB video card installed on my computer, i have a 19" samsung widescreen monitor running at resolution 1440x900.
what i want to know is if my graphics card will be able to comfortably handle this increase of resolution (to 1920x1200) and if so, how much will it slow it down.
i want the bigger screen to play games such as world of warcraft and TF2 which, at the moment, im having absolutly no problems performance wise. but will i still get a decent performance from games like crysis and Empire total war?

any help will be greatly appreciated
