Monitor resolution and gaming?

[diablo24life]

i have a vga monitor with max resolution of 1366 by 768. i have a radeon 6790 gpu. now if i play a game like skyrim, bf3 or any game and change the resolution to something beyond 1366 by 768 will it actually make a better picture? or will it top out at 1366 by 768 because of my monitor?

FYI when i say change the resolution of a game like skyrim i mean going into the game settings and changing the resolution to something higher in there

it will give better image on higher resolution but if ur monitor is of 1366x768 so the maximum resolution will be also 1366x768.
