This is a very noob question but... I'm thinking about getting a MacPro, and am looking at LCD screens on Froogle. Now, I last had an Intel iMac with a 17" screen, and a resolution of 1400x900, but the majority of all 17" LCDs seem to be at 1280x800. The only screens I can find at 14000x900 are 19". Now, a 19" is fine, but if it's stretching that 1400x900 over a further 2 inches than my iMac, will I notice a significant decrease in picture quality? I plan on doing lots of graphic design and gaming, so this matters quite a lot to me.
