for an 8800 video card if the montior is not at least 1600 x 1200 or 1920 x 1200 (or higher) you are throwing your money down the drain
unlike cheaper video cards which fair better on 1280 x 1024, a 768MB 8800GTX (or even the 620 GT model) need a very high resolution monitor or you wasted your money on the video card. It will actually perform worse -visually- on 1280 x 1024 and you wont be using the core/card you spent so much money on.
If you really want an awesome monitor that is full HDTV as well, I use this one and can highly recommend it..
http://www.newegg.com/Product/Product.a ... 6824014124Its very cheap now too. When I purchased mine a year and a half ago it was 1200 dollars.
Also, there is more to a TFT than just scale and MS response time. The monitor I posted above is using a 8bit screen processor where most cheaper units run 4-6bit and require at lease a 4ms response time to avoid motion blur and other issue. With the 8bit screen the 6ms response time is well under any motion blur issues and is good to go up to 160FPS without problems in that area.
The contrast ratio makes that monitor explode with realistic color and hue and delivers and excellent black level
If you are going to spend the money on the rig you did, dont skimp and destroy what you gained with the tower hardware by putting a cheap/low res monitor on it... if you do, you wasted your money on the rig
