I just recently got to act 4 inferno on my barb for the first time and it seems a lot of people can output a lot more dps and survive longer than me I've tried looking at some guides but the gear they recommend is way out of my price range I just bought a 400k amulet which is probably the most expensive item I've bought yet. I don't know how people get into the multi millions of gold so easily. Maybe they use the AH very well I find a lot of rares but don't know what's good or not and if it is how much it's worth. There seems to be a lot of research that needs to go into this game and I'm sure that will come in time.
So just looking for some good tips. Any ways here is my barb currently:
