Need a system upgrade for GTX 980 ti [2011 custom build]

[xinode]

Hello guys,

My current system has stopped working after two weeks of use.
It is due to the motherboard, cpu and ram not working with the new GPU i bought the GTX 980 ti, this was reported and tested by Australias MSY.

My current system is as follows

CASE Cooler Master: HAF X
CPU Intel Core i7 3930K
CPU Cooler Intel asetek water cooler
Motherboard GA-X79-UD5
Memory G.Skill Ripjaws 32GB DDR3 (8 x 4GB)
GPU GTX 980 Ti
PowerSupply 850 w
Harddrive 2TB & 1 TB Disk
Operating system Windows 10 Pro

Purpose of the computer:
Now, my main purpose for this system is for Simulation solving, Visual effects (Nuke), unbiased rendering and of course gaming.

What needs upgrading:
Im looking towards only upgrading the Motherboard, CPU, ram and hard drive. Want to have a solid state (under 500gb) and a standard 2.5tb disk

Budget:
1000$ AUD, buying from msy Australia, Adelaide

Overclocking:
Maybe

Notes:
The trouble shooters found out that the 980Ti doesnt work with the system, they tried three other 980tis from other brands in all slots to no solution,

They then tried there stock standard card and the system ran perfectly apart from faulty ram slots that was happening based on a 40% chance of failure, sometimes it worked some times it didnt but 60% of the time it was working.

Given how gray of the fault was and that they didnt charge me the trouble shooting fee lol, they said there best guess is that the motherboard, ddr3 ram and the cpu is simily to old for the graphics card.

Im planning on purchaes the different parts in two weeks once i have gotten a good idea on which parts seem best to replace What are your ideas on which is the best motherboard, cpu and ram?
1150 socket? 8 core cpu?, the default line has to be at at least 6 or more cpu cores and 32 gb ram.

Thanks,
Michael

There should be no reason that graphics card shouldn't work, with that board. What is the make and model of that power supply? That system isn't any older than people running a 980ti with a 2600k.

The power supply is a Thermaltake Toughpower XT 850W, i know there shouldnt be a reason to why its happening but it is, and its probably faulty if not comparability, either way the computer doesnt work with the card in ^_^, although im willing to take onboard other suggestions or work arounds, what would hypothetically be a good replacement for the cpu, ram, motherboard and harddrive?

What was your previous GPU? That PSU is not a very good model. I would suggest changing it to a proper tier 1 or 2 unit. Yours is a tier 3 model.

As far as upgrade, a 5820k would be the minimum I would go with, given what you are using now. Broadwell-E is coming, Q2, so it is not the greatest time to upgrade. If you have no choice, though, the 5820k is still fine. Hard drive depends on what kind of capacity you want, or if you are interested in stepping up to an SSD.

My previous GPU was a GTX 590.
Would would be the best tier 1/2 model power supply to get in the context of my current situation in terms of brand?

Evga G2 series would be my pick. Great PSU's, with a 10yr warranty.
