Lately i've had : 8800GTX, 9800GTX, GTX 260, GTX 280, 4870, and now 4870X2
The 280 and X2 will run any game maxed out with AA + AF on my 2560x1600 monitor (bar Crysis). They will easily cope with 1920x1200.
But for that res i'd got for a GTX 260 896MB, as 512MB will soon not be enough for that res (i'm always running out of memory on 512MB cards at 2560x1600, and can run into @ 1920x1200 on a handful of games with crazy amounts of AA + AF).
Plus the GTX 260 overclocks really well - see here. It will atleast match a 4870 if you clock it.
If you dont wonna overclock it, then for a bit more the 1GB 4870 would be good.
I agree the GTX260 is a good buy and does overclock very well indeed but the 4870 1GB is really poor value considering you can pickup a GTX280 for just a little more.
