His sticky and two of you recommend 8320's??

@OP: Personally, at your budget and uses, I would get this:

if you have a dual band router and want to take advantage of it, get this:

I know you don't plan to OC now, and you don't really need to for your uses, but just know that that CPU has great OC potential. So when you need more performance in the future, I would recommend an OC. It's not hard with a little bit of research or you can post here and if ghot is still kicking he'll probably write you paragraphs of how to.
As for OC'ing, you should get this either now or when you decide to OC:

It's a new comp so you'll want to wipe your existing HDD if it's been used previously. Either way, install OS, system files, programs, and commonly played games on the SSD for a major performance boost. Large, rarely played games and media file (music, movies, pictures, videos, etc) go on the HDD.
It's worth noting that if you think you're going to be doing other CPU intensive processing that you didn't list, you're better off dropping the SSD and grabbing a 4690k with a z97 mobo (probably PC Mate at your budget). However, between the internet, microsoft office, and gaming, you'll get much more benefit out of an SSD than 4 cores.
