Well there is not point in getting 1080p if your computer cannot handle the resolution. I am going to download the 720p because I dont want the lag. The lag didnt affect me at all if I didnt run in full screen mode. I have a 30 inch HP LCD that runs natively at 2560 x 1600. So I like to watch it in full screen. If your monitor is anything below 1920 x 1080 then there is absolutely no point I think in grabbing the 1080p version. My 2 cents!
