yeah get the monitor now as dx10 cards will be out soon. what you have to remember now that there is about 20% more pixels on a widescreen monitor and you will have to play it at resolutions of 1680x1050 not say 1024x768 so there will be more demand from games such as bf2. heres a good forum dedicated to widescreen monitors: http://www.widescreengamingforum.com
also see the product review sticky, i wrote a review in it about my widescreen monitor: http://www.computerforums.org/showthread.php?t=39148
the monitor you was looking seems good but the contrast ratio is abit small, its 450:1 were you should be looking at least 600:1. the rest of the specs are good tho.
