it should be. GTX460 should have no problem maxing out most games out there at that resolution except the one that very taxing on gpu but you should be able to play on high with acceptable performance
Yes, actually you will be able to play all the games till now fully maxed out settings, on 1920X1080 on GTX 460. I am doing the same.
Even Crysis 2 ran like silky smooth on my system on 1920X1080 on all the settings to 'Enthusiast'.
I dunno about every game and at 1080p.It would definitly take a strong CPU with the GTX460 to max out almost all games and your fps would be in the 30's.
