Xeon E5 2603 v3 for gaming?

Is this $200 Xeon E5 2603 v4 (6C 6T 1.70 GHz) good for gaming? It is cheaper than the price of an i5 6600 yet has far more cores/threads. Only concern is the very low clock rate.
Will it bottleneck in gaming?
RX 480 (GTX 970-980)
GTX 1070 (980 Ti)
GTX 1080

I have just finished my upgrade 4 days ago. My old spec are as follow:
i5-2320 3,5GHz
MSI z77A-G45
4x 4Gb DDR3 1600
deepcool iceedge 300 heatsink

was changed into:
Xeon X5-E26XX V4 with 12 core 24 thread but only at 1,7GHz (got it for $120)
Asrock X99 taichi
4x4Gb DDR4 2400
Intel xeon heatsink

I have only tried Division and Battlefield 1 for heavy game and War of warships for the light game.

They all perfectly well in those games. In division and BF1, my new cpu working less than 25%, mostly 21% with the cpu fan barely starting to turn as I set 50c as start working temperature (in game the temperature stay below 51c) . While in BF1, my old i5 working 90+% and sometimes hit 100%, temperature hit 68c.

BUT I know that division and...
I am using one right now with a Radeon RX 480 Red Devil and it plays ALL my games including Battlefield 1 on either very high or ultra no problem. I say go for it.

BUT I know that division and BF1 are using massive hyperthreading, so I am still have to test on less hyperthreading game (aka lazy developer).

I have checked in BF1, most of the time 4-6 of my thread are just resting (they are moving around between the 24 threads, but at least 4 of them are 0%)

They are beautiful cpu, even the old ones with sandy bridges are still kicking the butt when you use 2 of them in one motherboard. I saw a youtube that uses 2 cpu with 8c/16t each. Its killing BF1 with almost 12 thread sleeping. He might forgot the electric bill with using those 2 cpu. My cpu only uses 65W and 1 is more than enough.

My gpu is only 1060 though, I currently playing all game in fullHD mode limited by my old TV. 60 fps in ultra is guaranteed in all current game. I am too old for 4k as the letter was way too small for me to read.

So in conclusion, I would worry about your case since its only 6 threads with 1,7GHz. I would say its not worth the cost of the motherboard as 2011v3 motherboards are expensive. Either go with used cheap xeon or just go back to i5/i7 with latest release.

Good luck
