I'd really like to try an ATI out...I've only had nvidia so far even though a few years ago ati was better imo...I could probably only use an ATI for a month or two before crawling back to nvidia though...
And also, as stated before, I'm just not satisfied with my lcd. At first, I wondered what others were complaining about, but after coming back to my lcd after watching like tv or whatnot, its just way too dim. I've seen the HP's and Sony's in computer stores and they just seem to be a higher caliber
Light leakage and dead pixels are nonissue with me however
