Is raising the difficulty worth it?

Mining some on 50BTC pool right now and it sais for my 7970 I should raise the difficulty.  What does that do and how would that benefit me?

You are producing many hashes for the difficulty 1 which could lead to a high load on the server side

So you can increase the difficulty and for example only have to contact the server once instead of four times, but you also get 4 times the reward!

Cool, thanks Thoro.
