i am new here can some one recommend me good mods (fnv)

I suggest using dragbody's overhauls for the major factions. They completely remaster every outfit and NPC, and include new character models.

They're absolutely great mods, and have made my game MUCH MUCH more immersive and I recommend them if you want to make the factions stand out more besides having the old generic clothing that every NPC wears.

Quick and easy installation, and you'll notice the changes as soon as you start up new vegas.

Welcome to GUN @deadlylazer! Some GUN FNV mods I recommend are the faction mods @Bigman recommended, except I do not like Legion Will Ryse and actually prefer one of Drag's best faction overhauls and that is Caesar's New Regime, it has more flavor and actually adds in new stuff instead of just replacing stuff, I recommend some of the weapon mods on here, also get the hitman armor samplers when you can, they are pieces of armor that have been made available to the public from the private packs so check that out if you can. For non-GUN mods, I recommend IWS, Populated AND Repopulated Wasteland together (You're gonna need a good rig for that but just get Repopulated if you don't have a good computer), TTW, Get Weapons of the New Millenia, get some of the most popular armor mods for FNV on the Nexus, get Enhanced Blood Textures and get an ENB. Also if you want, get Project Nevada and the new gameplay overhaul that actually improves upon some stuff PN is outdated in. Get Hitman's Anim Overhaul but install Weapon Animation Replacers first so you can use WOTNM, also get Realistic Wasteland lighting and get an Nevada skies. Last thing I recommend is get an ENB compatible with Nevada Skies, most of the new ENBs are NOT compatible with NS so just get an ENB that is compatible, I use Dynamo and its freaking gorgeous. Other than that, I'm done.

See you around bud.
