A 4890 or GTX 275 is perfect for you w/a 22" display, more than enough actually... A 4870 or GTX 260 can easily handle 1680x1050 to be honest, but the slightly faster 4890/275 gives you a lil' headroom and/or extra slightly more AA in a few tittles. The same cards could actually handle a 24" display (1920x1200) with some AA in most games. They're so close in performance I'd just go with the best price/bundle you can find, seeing as the insurance company is footing the bill I'd pay a couple bucks extra if needed to go with an XFX card (if going ATI) or an XFX/BFG/EVGA card (if going NV) so you get a nice warranty and good support down the road.
