What are the averages that most people achieve on our card?
1200/1500 is the median I would say. Most cards can reach this. And memory OC can vary with bios and memory manufacturer.

Depends on the price. If you are going to sell the 7870 xt for say 150 and picking up a 7970 for 300 then I would say no. At best the 7970 is 20% better when overclocked than the 7870 xt overclocked. If you can get it for 75$ after selling etc then that is a good deal.

That's pretty close to the definition of innovation.

Something I never knew and I might as well ask you guys now since a lot of you are replying; Better to be pushing the core clock, or the memory clock? Which will have a bigger impact?

Core clock by far. Memory probably won't even make a difference past 1600.

Yup core clock is a bigger factor. Memory overclock over stock had no effect on benches and framerates when I had it set to 1600 mhz

IMO, that's still kinda hot, mines maxing at 63c on stock clocks undervolted to 1038mV @45% fan and it's around 30c here.
