CGRemote absolutely worth it if you are mining on several rigs. If you have only one rig there is no need in it.
about sick or dead gpu. Ive had the same problem with my r9 270. It went down twice a day approximately. Ive just decreased intensity by 1 and raised voltage a little bit for one or two days, then turned everything back. Now its running on 502 khs without any problems.
i have my 25 mil zeit stuck on coinex, deposited everything 4 minutes before it went in maintenance mode (((( hope i'll see my coins again
zeit to the moon
hope we'll see block explorer soon...
