Need to Play Fallout 3 Before New Vegas?

I can't decide whether to pick up Fallout 3 or Fallout New Vegas for the PC since almost everyone says it is the better version. My main question is, is there any story that is related to Fallout 3 in New Vegas? also will miss anything relivate in Fallout 3 gameplay wise or does New Vegas have similar gameplay

Fallout 3 is great, I had it without the DLC. If you buy the GOTY edition it will be good. But its not needed to be played before NV. The storys don't connect.

From what I hear FONV is an improved FO3. And the stories are completely different. FO3 is still a fun game but I would just go ahead and play New Vegas.

New Vegas has new things in it and improvements to the gameplay, although the downside is that it has a lot of the bugs from Fallout 3 as well as a bunch of new ones too.
