The AMD vs Intel thing at this level I think is tied a lot to the size of your case, how big a cooler you can fit and what programs you are running. The AMD 760K for FM2 socket and the FX 6300 for AM3+ socket would be your main options I think. The 760K is ~$80-$90 while the FX 6300 is usually around $120. Both can be found cheaper used on Amazon or Ebay.
The intel options, you can go with a i3 3225 for H77/Z77 chipset (Ivy Bridge) or with the 4330 that you are looking at. Check all processors for used prices at this range, there is a lot of turnover and both seem really reliable from my experience.
