do I need a powerful cpu for small file server/ rendering server

[thegoogler]

I am planning to build a master and slave single pc server for occasional rendering for buildings and just for normal file storage but am wondering if I am going to use a 970 or a Low ish TDP GPU like a quadro for rendering or a more power hungry card like a tesla gpu?

do I need a good powerful cpu to handle it or like mining rigs that just have a pentium and 5 rx580's does it just matter how powerful the GPU is??

I want to know so that I can know if I can buy a cheap 35/20w dual core cpu and user the rest of the spare wattage on other stuff or should I just go cpu only and get a 8/10 core intel xeon e5-2650/ 2650v2 etc and have a very low power gpu to assist?

What software and render engine?

[NelizMastr]

As usual, which hardware you need depends on the software you're going to use. Some software runs considerably faster on a workstation card, some software doesn't care, and some software actually prefers CPU rendering. 

 

So, which software?

To me it honestly seems like you have no idea what you are doing, so you shouldn't do it. 

 

If you don't even know what kind of resources your programs need, then you should start on getting more information about that first. 

After, you should look into the differences between GTX, Quadro and Tesla, as they are all meant for different scenarios. Tesla even more so.

I am using blender open GL or CL rendering, sorry I forgot to mention it

I know what I need I just don't quite know how to form the question I need to be able to remotely render from blender when I am at college and I need to be able to backup files from college so I want to build a server which is low TDP but am wondering what I should allocate more power to.. I hope that makes more sense

Would you explain why TDP is so important to you please?

ok in Australia power is expensive it is 0.25 AUD per kilowatt hour

kW is 1000 W, typical computer can use about 250-350 W in stress, so it's max 0.35 kWh per hour, it's about 1 kWh per 3 hours. So 8 hours of using computer is 2,6 kWh, so it's 0,65 AUD. I don't think is that much, especially if you're not using it at 100% CPU power all the time.

ok maybe I messed up something, i don't know but yeah I want to spend as little on power for it as possible
