Unless you know something i don't, i doubt you can find new Annies for $300. They sell for $500. The Q701 would be obtainable at that price. I'd consider lowering your budget if you're MAIN use for them is gaming. Music wise i can understand the jump, but it depends on your needs/wants.
I can tell you the mixamp will do ok with the Q701 with the volume on max, so i assume the same for the Annies. So for the gaming standpoint you would be ok with just the mixamp. However where you're going to want a dac/amp in the chain is for the music. I would absolutely recommend buying a set for general music listening. I use my Q701's for pretty much the same exact reasons you have listed, equal parts gaming and music, with use for movies every now and then. I have to say i'm 100% satisfied with this set up.
I'm currently using a AntLion ModMic and i'd recommend it, weather you have to wait for it or not (it goes out of stock). I have no problems getting acceptable volumes while gaming using just the mixamp, and the mic is pretty high quality.
