for 1 19 inch monitor at 1440x Resolution get a 5770. a 5850 will be completely wasted at that resolution. The 5770 might have a smaller Bus ( the 128bit) but its using GDDR5 RAM, which makes it better then the 256bus your 9800gt was using buy a fair amount.

Yea for that rez, I say get the 5770, although you should honestly look to upgrade teh monitor; you are limiting your gaming experience. The money would be better spent on a monitor.
