I updated last post a little~

Set fan curve too when playing with GPU. You can do it in MSI afterburner, you just have to enable it right and then set it. You can make a curve, or just set minimum fan at 40c, maximum fan at ~77c with hysteresis 8c.

You can use a less steep curve but many of the gpu boost 2.0 GPU's just throttle all the way to the base clock if they're hitting 80c (and 80c temp for a small fraction of a second might only read ~78 on msi afterburner or gpu-z) which can be terrible. In some cases, it can mean losing a huge percentage of your GPU performance - reference 970's are 1050mhz base, but can somewhat regularly do 1550. That 500mhz loss is huge :D

You shouldn't be running Furmark for any reason. +6mv won't do anything, it might trigger a voltage bump but the volts can only go up by +25mv. If i set anything from ~+13mv to +87mv, i get exactly the same behavior because of where the stock voltage is and the voltage cap. You should either leave it at +0mv or just max out the slider, after verifying that it caps correctly (99.9% sure it should)

6 years ago furmark was dangerous but useful if you knew what you were doing and had a GPU with overpowered cooling and overbuilt+cooled VRM's (most 970's don't qualify there). Now however it's simply useless for any reason.

You should get the 4690k. I do not know of dota 2, but sc2 and csgo will be CPU bound whenever you're dropping near those framerates with even a 960 (which is like, 1.65x weaker than 970)

Even if you had a situation where you could get a CPU with HT and more encoding performance, game streaming performance hits are wonky and the CPU that simply runs the game the fastest in the first place (this can be a fast dual core for some games, or an oc'd 4690k instead of i7 etc) is generally what you want for the highest ingame FPS while streaming.

In this case though, 4690k + OC is not only faster for running the games, but also has more encoding performance because the clock speed gap is big enough. It's the obvious choice.

Also NVENC should be good for you (on the nvidia GPU's). A few button-clicks away in OBS and configured properly, the upgraded NVENC on newer maxwell GPU's is actually very good. You're basically just trading off some encoding quality for zero CPU load(*1) and often more importantly - no real performance hit(*2)

*1 - all encoding done with NVENC on the GPU, it's an additional encoder so the GPU performance itself is also unaffected
*2 - you need a consistent benchmark to even show a performance hit in many situations and you can't feel that it's there, even if CPU encoding with OBS, Xsplit or similar programs can make games feel weirdly laggy at times

Some time next year we should get new process (~14-16nm instead of 28nm which has been used for over 3 years) as well as HBM on mainstream GPU's AFAIK~ (stacked memory for much higher capacity and bandwidth)

If you want to buy before then, the 970 is actually pretty much the 560ti equivalent of current gen and the 290 is its AMD rival for graphics performance

I've not been up to date with SSD prices but $90 for a 250GB 850 EVO, what the hell. Only been about 2 years since I got my 120GB version and the price has dropped so drastically.

edit: Must resist urge to splurge
