GPU Overclocking instability, lower framerates after GPU clock increased

I'm having an interesting problem in the case of GPU overclocking with my computer. After buying a used GTX 970 to replace my older 960 in my computer, I read up about the 970's fantastic overclocking potential. But I was skeptical, as every other GPU I tried overclocking on this mobo ( A GTX 745, XFX AMD Radeon HD 6850, GTX 960 and now a 970 ) generally came out unstable, the GPU often crashing and offering lower framerates than before, even if Heaven showed there was no artifacting on the screen. The strangest thing is that while messing around with my GTX 970 a bunch, I found overclocking the memory gave slightly better framerate and I could go very far into overclocking it without any crashing or artifacting. But the second I bring GPU clock up, on any card I have tested, the reliability goes out the window, and to a point, the framerate averages start getting worse. I also upped the voltage a little bit but that didn't do anything, either. Is this a motherboard problem, as this is a stock Dell board from a XPS 8700? It also has its stock i7-4970 and 16 GB bog standard 1600 mhz Hyundai/Hynix RAM. Any help would be appreciated!

DO NOT OVERCLOCK ON THAT BOARD! :eek:
It's an all in one unit not designed for overclocking or even a graphics card, the power supply is likely underequipped for the job.
Don't even try to run the 970 in there, it could potentially fry your whole PC.
If you can, get a new power supply like the new Corsair CXM 550w (black label) to replace it.

Oops, my phone did something odd and selecte that answer as correct and now I can't deselect it. Oh well. Still, I forgot to mention that i did replace the PSU long back, with a thermaltake 600w one. So it's 100w over minimum wattage, and even much lower wattage cards faced the same problem before it.

Ah, very well. And if I were to buy a new motherboard designed for gaming and with the same slots for the ram and CPU, think I could put the processor and ram into it no problem? Sorry for the stupid question, would just like to be sure.
