3770k is like.. hmm... the double of 8320
and i've seen the 8350 vs i5-3570k and the amd wins like a boss. and in streaming it kills
well, depends... AMD is a rollercoaster.
The problem with AMD is that it is optimized for multithreaded tasks - if you encode/stream video it owns the i5. But if it comes to everyday tasks and playing games the i5 wins over the amd /since games run optimally at 2-4 cores and intel has higher core per clock performance/.
tl/dr> peterisluego is right - If you're building a dedicated video editing machine on which you'll play games from time to time - go for AMD. If you plan on gaming and edit a video from time to time go with i5. If you want to do everything like a boss go for the i7.
