1. I prefer EVGA precision - It has just worked better for me in the past. (But to be fair I had more experience when I used it)

2. Yes... And you can probably just jump the shaders to 1512. (1476 is you want to walk first )

3. I like to bump the memory also and keep the core close to what it should be if it were locked, but that's just me. Many here leave the mem at stock and drop the core below stock.

4. Furmark - yeah I mean if you really want to. I have yet to see a card that can't do 1476, so I would recommend jumping there and testing, then going to 1512. Also, GPUGrid itself is a much better test of shaders than Furmark. I would just try it (disable network so you don't burn through your Queue though)

5. When I had two, I did both in tandem until I hit a problem, dropped both one step and bumped up each. (Turned out neither could get above 1512 without extra volts though... and one card couldn't overvolt)

6. I don't worry about Furmark temps...If it's below 70C on GPUGrid I'm happy. I even run up to 80s in the summer - but not for long stints. Only gets that hot during mid day. But then again I'm not very cautious about temps. I say it's going to be old in 3-4 years so I'll get rid of it before I'll ever kill it.

I believe that's everything, but I'll go through this more thoroughly later. Feel free to point out anything I overlooked.

(And get that 920 OCed! Vcor 1.275, VQPI 1.300 mult 21 bus 180+ easy - maybe even 200 for 4.2 Ghz. With your cooling you're golden )
