Couple of questions about my AMD 5770

[2NE1]

Can a 5770 handle games alright at 1920x1080 or will it push it too hard? I'm using a 1600x900 monitor right now for WoW and want to try some other games. I do have a 1920x1080 monitor but I'm just wondering if its even worth using with my card.
Would I be able to get decent fps in Skyrim at 1920x1080 with that card? thanks!

I don't think a 5770/6770 would be suitable for 1920x1080 gaming. WoW might run but skyrim may not run (unless you turn down the settings). If you want to game at 1920x1080, I recommend 6850/6870. Though you will need a better power supply.
