Yeah.
I am running Far Cry at 1600x1200, all the video settings maxed out. I am NOT using any AA nor AF though. But the game looks just beautiful with these settings. FPS run between 45 and 80. I'm not sure about your LCD though, I use a 17in Trinitron CRT. LOL, I think that monitor is the ONLY thing I haven't upgraded in the past 4 years, but I do love it, a gorgeous picture.
I will say that one of the first games I ran with the x800pro was GTA3. I had upgraded from a GF4 ti4200 and I could never play GTA3 over 1024x768, and it was still a little choppy there. The x800pro plays the game at 1600x1200 with AA and AF at high, and it's smooth as hell. Liberty City never looked so good.
My other specs are in my sig...
