CPU upgrade real world speed increase?

[gerr]

My main gaming/encoding rig has an i5-4690(non-K) with a GTX 970 CPU. I am thinking about upgrading the CPU as I can use that current i5 in another system with a much weaker CPU. My main system splits its time evenly between gaming and video encoding(CPU based). I am wondering what type of real world speed increases I would notice by upgrading the CPU?

My two choices are...

1. i5-4690K. I can OC it to around 4.4Ghz as I already have a Z97 mobo and a Hyper-212 EVO cooler in the system. This will of course speed up both the gaming and encoding, but what type of real world increases would I see in both?

2. Xeon E3-1246v3. This option probably wouldn't speed up the gaming by much, but the hyperthreading and extra cache should speed up the video encoding by a good amount. The question is how much of a real world speed increase would I see?

I am still researching which option is the better one, but getting a ballpark real world speed increase would help me with that decision.

Well if you do alot of video encoding/editing/rendering an i7 or Xeon will improve performance by fair amount. i5's are very good at gaming, especially overclocked. 4690k at 4.4ghz+ will beat that Xeon in any game due faster single-threaded performance.

it all depends what are you doing with your PC.

What software are you using for video encoding? Usually gpu encoding is much faster than cpu encoding.

Right now, I am using Handbrake, but not the QuickSync enabled version as I have heard that while much faster, quality is much lower.

You might give it a try. Quicksync is much faster, and obviously you don't want to trade a huge quality difference for the speed benefits. However the newer haswell quicksync is supposed to be much better visually than the original quicksync. If you try it and still don't like it you'll know for sure but if the visual quality is still very good with much faster encoding on quicksync it may be a factor in which cpu you choose. To my knowledge handbrake's only gpu acceleration supported is quicksync with igpu, no support for offloading to nvidia cards (or amd/ati for that matter).
