Widescreen gaming can really be touchy depending on how powerful your computer is. If you dont have a powerful CPU and graphics card, it can be very difficult to play games in the native resolution that will make your mointor actually look good. That is the problem I am facing.
Because of my widescreen monitor (one of the Dell deals a bit ago), I ended upgrading everything in my PC - processor, RAM, motherboard, and video card, just so I could take advantage of 1680x1050 widescreen goodness.
But boy was it worth it.
