Displays How big differnce in 1680x1050 vs 1929x1299 in crysis?

I am playing very high, 4aa and in 1680x1050 and want to know if it worth it to go up a level would i even notice a difference?

Edit: 1920x1200 i did wrong sorry so how much better?

 

Don't you mean 1920x1200?
And is that Crysis or Crysis Warhead?
And which GPU do you have?
I play Crysis Warhead at 1920x1200 in DX10 on max. settings and 2xAA. It's gorgeous.

 

The bigger the better, but depending on what you've got now it may be an expensive upgrade for not a lot more.

 

Ya sorry

 

All i need is a monitor since my pc is already to line specs:

1920x1200 is definitely worth it, especially if you can run it at high settings like you will be able to

 

Impressive. You could even stretch to 30" 2560x1600, but you'd have to turn down the AA.

 

Ya i running it was running get around 39 fps average just walking around and drops to 25-30 when huge explosions happen and such and this is with nothing overclocked. Then overclocked gpu max and now getting 42 fps average.
