I'm debating whether I should upgrade from my 2600 non-k to a 6700k. With the motherboard I have, I am unable to turbo the CPU at all so I am stuck at 3.4Ghz. With a 6700k, I would plan on going to about 4.5Ghz. I primarily play games and stream music/videos, with the occasional video rendering. Is there a significant performance increase? Money isn't really a concern for this upgrade, I just don't want it to be a waste. Thanks!
