Yer 720P is ok for gaming with the Wii or older consoles.
If you want to use it for 1080p which some PS3 and X360 games do support(and certainly on PC) ,you need to get a real 1080P display 1920x1080 or 1920x1200 my 24 inch widescreen Dell monitor does ok i use a HDMI to DVI-D cable and the standards have slight differences which can cause problems though i am pretty happy with it - only one Blu-ray a small extra feature on planet earth on blu-ray would not work with the HDMI connection so i used component instead - everything else including all the other Blu-ray disks work great ovet the HDMI to DVI-D at full 1080P .
Get a smaller monitor with the full 1080P - if that is all you can afford.
If you want to watch Blu-ray or Hd-Dvd or 1080i off-air the full 1080p monitor is the way to go - also 1080P makes a very good computer monitor for desktop publishing - cad , viewing documents etc a 720 P monitor will be crap for this.
1080P is well worth the extra cost or going to a smaller size for they cost more but consider you get over 2* the number of pixels with the 1080P and Vision is the most powerfull sense so do your eyes a favour get 1080P if you can.
