Buying an new hd monitor and worying will my pc handle it

hello everyone i just registered so i wanted to ask the community about my pc and monitor
right now im using an 17 inch 1280x1024 and its nice but i really wanna enjoy gaming in hd preferably 1980x1080 i found a nice 24 inch but i was wondering a couple of things first off here is my rig
CPU:i5 2500k 3.3 turbo 3.7 oc 4.5 or more
GFX:MSI GTX560Ti Hawk 1gb also very overclockable
RAM:8GB DDR3 1600mhz kingston
MOBO:MSI p67-c43 (B3)
PSU:Thermaltake Toughpower xt775W
HDD:WD Caviar Black 1TB (expensive son of a bitch)
and the case really isnt important but for the curious ones Thermaltake Commander MS-I (didnt want to spend a lot on the case and this one was nice)
so now that you know my pc i would like to ask what kind of frames per second would i be looking maxed out in 1080p in games like far cry 3 metro 2033 last light crysis 3 hitman absolution assassins creed 3 watch dogs metro 2033 crysis 2 battlefield 3 and such if i can even max them out i wont be using antialising since i dont really notice it and i can always use fxaa via nvidia control panel here are the frames from some of the games i played in 1280x1024 res
Crysis 2:Averages at 55-60 sometimes 70 with dx11 and high res textures 60+ 70+ when i oc my graphics card havent tried with oc d cpu yet
Metro 2033 utside i get around 50 sometimes 60 average when overclocked gpu 60 and more
Battlefield 3: i haven really run with fraps but i think its 60fps stable or more with all ultra and antialising note that when i turn tesselation off in metro 2033 outside i get an average of 70fps
Max Payne 3:runs at 60 70 80 with 0 overclock so how do you think il run all the games i mentioned at hd res and is my pc enough i really hope it is sorry for the long post and thanks in advance
