I'm not in the market for high-end GPUs, my max budget is probably £150 or less, so not for me. Also, my last GPU was an 8800GT which bumbgated (as did my brother's, and I've also personally seen 8400GS, nForce 7100 plus lots of laptops which bumbgated), so I'm unlikely to buy Nvida again... I don't game much but that was the highest level card I ever bought (for myself) and I'm not going to forget the incident any time soon :-(
This is surprising, maybe there's something wrong with the miner? I expected it to achieve at least 450-500 MH/s
I'm not surprised, Nividia took out most of the compute parts of the chip, a recompile may achieve a bit more but I doubt it will be a high %. Unsure if mining is double precision or single, but DP is very low on the 680.
As usual the hype with Nvidia launches is huge. Fair enough, the 680 performs very well in games and it's amazingly efficient for Nvidia but it certainly has issues too. Poor compute (which is fine for most people of course), so-so PCB construction (it really is mid range) and that suspect auto boost.
Now CPU Turbo is fine by me, but because this Boost is based solely on thermals which in turn are based on the cooling of people cases
plus the binning of each chip, it is very hard to predict what exactly the average
stock speed is going to for someone buying that card. In general though I am sort of in favour of the Boost but I do think reviewers should be a bit more careful with it since is in it effect a YMMV auto overclock rather more predictable CPU Turbo (max this Turbo and no more).
