Noob question regarding resolutions and performance

[Inu]

I know im gonna get an LCD and im thinking about getting this AG Neovo AGM CW-19 Black 19" 8ms Widescreen LCD Monitor 300 cd/m2 500:1 0.285mm Pixel Pitch or a different non widescreen monitor. But in either case the resoulution is gonna be 1440x900 for wide or 1280x1024. Im wondering which resolution is gonna be stressfull on a graphics card. I dunno exactly how to figure that since one is a widescreen resolution but if you multiply the two dimensions for each the 1440 reso equals less pixels but not by much. Although i still dunno if thats an offical way to test something like this. Anyone got some insite into this? Any help would be appreciated

Performance should be roughly the same in either resolution. There's nothing special about widescreen that makes it perform any differently, unless you use an ultra-high resolution. Stick to 1440x900 as much as possible, since 1280x1024 would always appear either stretched or 4:3 with black bars on the sides.
