Random Shutoffs and Abysmal Performance

So, I just installed three new components: A 1TB Western Digital HDD, a 750w Gold XFX TS PSU, and an XFX R9 380 2gb.

My PC before the upgrade had these specs:
Asus P5Q Motherboard
Core 2 Quad Q550 @ 2.83GHz
4GB Ram (I don't know the brands, this PC was given to me by my Uncle.)
Radeon HD 4550
Antec 450w PSU
250GB HDD, also unsure of the brand, I believe it's probably Seagate.

Since installing the new PSU, GPU, and HDD -- I haven't formatted it yet -- my computer seems slower; it can't launch Skyrim or Fallout: New Vegas at all, Diablo 3 FPS is pathetically low at lowest settings, and Elder Scrolls Online causes the entire system to shut down as in, if I try to enter the game, it shuts down, if I try to raise the graphics, it shuts down.

I honestly don't know what the hell to do at this point. I bought the R9 a couple of weeks ago, but held off on installing it because my power supply didn't have 6-pin PCI-E cables, and now that I have a power supply that has them, the damn thing doesn't work.

As I said earlier, my entire system seems significantly slower. It takes longer to boot, and just scrolling through steam seems choppy. I don't believe it's a GPU temperature problem as MSI Afterburner only shows a max of 50 degrees Celcius. I also have the latest AMD Drivers for my card.

Is this a faulty PSU? Are my processor and motherboard too outdated to utilize any of this?

Any help is greatly appreciated.

P.S. I got a playable frame rate in Diablo 3, Elder Scrolls Online, and Fallout: New Vegas (with graphic mods) and now I can't even run these.

P.P.S. I also am entirely unsure where this would go, exactly.

Would you like a stress test or just idle temps?

And I mentioned GPU temps because of the horrid performance in those games, which doesn't make sense to me.

Alright, so there's two things I've seen. I'm looking at both Real Temp and CPU-Z and I'm seeing some things that definitely aren't normal.

First off, Min/Max Temps for all four cores are as follows: 92/102 86/92 86/95 85/94 degree Celsius.

Secondly, the CPU is underclocking itself to 2GHz on its own, and still running that hot with 2-15% Load on it.

My CPU has never run this hot, what in the world is going on here...?
