Will my screen resolution greatly effect my performance?

If I have 8 gb of ram an amd 7850 and an fx 6300 in a gaming computer, on demanding games such as bf4 how much fps/performance drop will I see between a 1080p monitor and a 1366x768 monitor?

A 1920x1080 monitor has 2073600 pixels. A 1366x768 monitor has 1049088 pixels, or roughly half as many. That's a MUCH lighter load for the graphics card. If you go from the smaller monitor to the larger one, your FPS could drop by close to half also, although it will also depend on how demanding the game is on your CPU. If it is at all like BF3, expect BF4 multiplayer to depend a lot on the CPU for performance too.
If you're concerned about the larger monitor sapping performance too much, you could: 1) run it at less than its native resolution for games, although that could introduce some fuzziness or unintended blurring, 2) get a 1600x900 (1440000 pixels) or 1680x1050 (1764000 pixels) monitor instead, 3) turn some settings down, or 4) get a more powerful graphics card, like a HD7970 or GTX770 instead.

Well 1920x1080= 2,073,600 pixels, while 1366x768= 1,049,088 pixels. If your card has twice as many pixels to color, i would expect the performance to drop a decent amount, probably about 20 fps, but it depends on the game.

...beat to it again, amazingly similar response Onus...great minds ;)

How much would the performance differ between a 1366x768 and a 1600x900 monitor?

Well, 1049088/1440000 = ~0.73, so at worst, you might see only 73% of the FPS you were getting before, but again the CPU load will affect that too. If you were getting 70FPS in a game, you'd still get at least 51FPS, which should still be smooth and playable.
