Hi, I have a gaming rig, a mining rig and freenas rig.
The mining rig is i5- 4670k and 3x r9 290x 8gb ram. With full intensity mining the pc is very slow takes a while to load a double click. When intensity is lowered performance improves but the kh/s decreases. the gaming rig is i7 4770k 8gb ram and gtx titan. I mine whenever im not playing and I can run a browser or 2 or office during. But I have to stop mining when I play. I want to consilidate to 2 rigs. Freenas/mining and gaming/mining I will be adding more cards and replacing the titan with amd for mining and gaming. For freenas/mining I need a cpu that can definitely handle both 24/7 smoothly. For gaming/mining is there a cpu that can handle mining on 3 cards for example and gaming on the 4th? I know about desktop cpu's but can xeon or ws cpu or duo cpu handle this? if so which one? Thanks for all the help...

Edit: im gpu ltc mining using cgminer

Mining is designed to use 100% of the load.

I'd adjust the mining program. You'll need to tweak and prioritize the application. If you are running Windows on the mining rig, consider a base Linux install.

Updating the CPU will just allow the mining program to use more CPU and gave the same results. You need to adjust Linux to give the mining program less priority or use less CPU.

It's a service, it just uses whatever you throw at it.
You can build a 1 million dollar super computer, and the program will still utilize all available resources. That's its purpose.

You need to limit the programs functionality. The program uses 100% of any resource you give it. You could consider an 8-core chip, like the FX8350, and there's a chance it will only fully utilize 4 of the 8 cores.

Otherwise, just limit the program to use only 3 cores and leave one remaining.

It doesn't matter what processor you run Prime95 in, it's designed to utilize 100% of the CPU.

It's the same for the mining app. All processors will be slow.

The current set up is best. Finding a triple crossfire capable 2011 will be near impossible. The CPU does so little work compared to the 3 GPU's, you can easily disable it with little or no impact. You would gain much more performance from 4x GPU's than any CPU upgrade.

Your best option is just to toss in a small 60 GB SSD and run 3 cores + the GPU's, than host a 1 core VM with most of the RAM, that is linked to the storage drives on the NAS.
