1. About 70degC iirc.
2. The temperature registered by the core increased by a degree or two but this could be due to the increased case temperature as a result of increased memory chip temperatures, not sure to be honest.
3. The temperature increase when I tested via infrared gun pointed at the chips compared to stock and at 1700 was around the 10-15% mark and at 1800 it was near 20%, what the exact temperature was I can't recall.
4. The memory chips on the core side are cooled directly by the block, the chips on the rear are passively cooled via a back plate and also I added some thermal pads to the underside of these chips so they get some cooling from the water block also.
Before wc the max stable memory clock was +660 resulting in clock 1832 and after wc the max stable was +732 clock 1868. In my case the overclocking was limited by temperature under air cooling since you can see the chips still had more to give when under water cooling. For reference when benchmarking for max overclocks my fan profile was set to 100%.

The stability problems were rectified in most cases with an official Asus released TOP bios update. If you were to buy the 670 you should still have manufacturer warranty remaining since they come with 3 years and the card has only been released for little over a year.

Why couldn't have I gotten a 680 when I RMA'ed???
