gaming Fallout 3 Goty Which Mods Should I get?

[Revy ~ Two Hands 862]

Okay so I just bought Fallout 3 Goty off Steam I used to have it on Xbox 360 about 5 years ago. 

My question is what mods should I get for the pc version and why?

 

My Pc specs are as follows:

CPU: AMD Turion II P520 Dual-Core Processor 2.30 GHZ

Graphic Card: Radeon 5440 HD

RAM: 4GB

OS: Win 7 Home premium

 

Bear these specs in mind because I want the game to run at a smooth 60 fps so although I want custom or improved graphics I don't want any mods that will decrease frame rate below 60.

 

Thanks in advance!
