Recently got a GeForce 980 and tried installing it over the weekend only to discover I had the wrong cables (6+2, needed two 6s). Went through my kit and found the correct ones, however I still had no display and I could hear the PC booting into Windows. So I might need a BIOS upgrade. My co-worker and a guy who's far nerdier than me has the same PC and situation. Neither of us can figure what's causing the hangup on our PCs, so I've got a call out to tech.
That might be good timing because...
Started up a MW:O match with Gordo tonight and it was like playing a slideshow. Figured maybe it was because I didn't put the nVidia drivers back on, and possibly because I installed FRAPS today to resolve my Legendary issue.
As it turns out, my CPU was overheating. I can still do normal shit like forum posting (although I'm typing this after leaving it off while I watched 47 Ronin), but gaming is out.
So anyway, long story short, I'm out of gaming until this is resolved. Hopefully, it won't be too long.

So the old card is back in and you have low frame rate? Or you got the 980 working, but with low frame rate?
Have you checked your power saving settings? 
How big is your power supply? Maybe the 980 is more power hungry than the old card. Also, high end power supplies have two . . . channels? I forget what they call them (might be rails). But it amounts to two circuits. Both are 5amp or something (varies from one PS to another). Maybe one of your channels is being overloaded if you have everything plugged into one of them.

What model exactly? And yeah, first thing I'd check would be the hard and soft power situation. Get a benchmark rendering test. See what's up. Also, overheating by how much how fast?

Old card is back in with original cables. All work was done far away from the CPU.
All fans are running.
My power supply isn't the issue and the 980 actually uses less power than the 580.
It's overheating enough to where I can't play games, but I can still do email and web surfing, although random slowdowns occur.
Run diagnostics to try and figure out how quickly. Although, it's obviously not fast enough to shut the PC down. Went through that shit in the old AMD days.

It is only overheating with the 980 or as well with the 580?

980 hasn't been in it since Friday. Overheating started late last night. Looks like 15-20 minutes before the system powers down due to heat.
Not good.

Trying to figure the issue:
1) Your CPU is overheating when you game with the 580?
2) The GPU on the 580 is overheating when you game?
Unless you have some obvious ventilation problems, I'd check out the cooling element(s) present and make sure they're working as they ought.
Other thoughts:
1) Is it now or has it ever been overclocked?
2) If the vid card's got miles on it, the GPU might be fucked only with a high enough workload. It does simple things easily. Heavy lifting kills it.

Even though you didn't bump it, I'd still check the cpu fan. Gordon's was installed incorrectly, maybe yours was too and it finally jarred loose while the case was being handled for these installs. I can't imagine a software issue could be causing overheating. It's got to be hardware. And that's obviously the fan. I'm assuming your heat sink isn't clogged with dust. So it has to be the contact between your fan and CPU. Last thing I would check is the power/fan settings in bios. Are they set to adjust the fan based on heat, or on full blast all the time. Try setting them to full blast all the time. Perhaps the MB isn't detecting temps correctly and applying more fan.
Set up a tent in the back yard and game outside.

Even after fixing my CPU fan I have found that having 10+ pornographic Flash movies open at the same time will cause overheating.
Just FYI.

And this is the right time of year for it, so that's lucky.

Maybe try cleaning off the old thermal compound from the heat sink and reapplying some new compound. Make sure its setting on the CPU correctly and reseat the fan like Cake said.
Is it your CPU that's overheating or the graphics card?

I'm leaving work early today to try some more stuff. I will attempt everything you guys have mentioned. I do have more of the thermal compound I can put on, and while I doubt the fan is ajar as it screws down, I'll check it out.

I would think:
1) Check/re-apply thermal paste.
2) Check heatsink/fan connectivity.
3) Make sure fan is working.
4) Point additional fans at it and see if that helps.

Don't know how often you do it, but I used Q-Tips and rubbing alcohol. I was just careful and didn't even remove the CPU from the mobo. Took my probably 3 minutes to gently rub the old paste off the CPU and sink.

I've never needed to do it before.

Back in the day when I built my first PC, the paste did not come already applied to the heat sink. I learned then how to remove excess. Haven't done it since, until the other day.

Still have to do that for the custom cooling elements. Don't slather on the paste to begin with.

Fingers crossed that I'll be back online Friday night.
My return is dependent upon when the new parts arrive, then I have to start at square 1 to put the new video card in, which is a separate issue that I've figured out during my down time.
So what was the issue? Well, and again, this is assuming the new parts do resolve it, but all signs point to...something nobody has mentioned.
Why has nobody mentioned it? Well, it IS a hardware issue, however when I first posted this I had completely forgotten about this because it was hiding in plain sight. So I've never mentioned its inclusion in my system. Plus, I've never had one in a system before. I completely overlooked it Sunday, and then realized Monday that I was doing that. After some odd testing I realized that was the issue and ordered the parts.
Any guesses?

Bad temp sensor?

Water cooling system sprung a leak?

Malcolm wins.
My water cooling system is so small and out of the way I forgot it was in there. Never had one before.
Although, it's not a leak, but rather the pump appears to have failed.
Was doing some really odd trouble shooting the other day tilting the PC at different angles while it was running to see if there was an air bubble that needed to be freed up.
