I have another one called the unified hud projectthat lets you move the HUD around and add extra things like carry weight and current rad count and even a clock. I can't remember which HUD mod does it, ethier Darnified UI or MTU that make the interface less ridiculously big. 4gbNV also helps with performance, especially if you intend to get HD texture packs. ABSOLUTE essentials are New Vegas Script Extender, which most mods need in order to work, and get New Vegas Anti Crash and New Vegas Stutter Remover to massively improve performance.
