So this week the power brick to my 30" Apple Cinema display decided to stop working. It's overheating and I hear a clicking coming from it while my monitor no longer turns on. I've looked for replacements but they're all but impossible to find (new that is). I've come across these Chinese knock-offs on ebay http://www.ebay.com/itm/Apple-A1098...0W-for-30-DVI-Cinema-HD-Display-/271037716125 or otherwise have the option of paying for a used one. Given the age of a used brick and the questionable quality of Chinese counterfeits I started looking around craigslist and have seen some cheap thunderbolt displays. The problem is that with my upgraded 5870 I'm unsure whether the mini display port works with the thunderbolt display (I've gotten some conflicting statements). If they're compatible this might be an economical solution until announcements are made this year. Ultimately I'm waiting to see what 7,1 brings the mac pro in which case hopefully a display may appear along side it, so investing in a totally new monitor might be premature. At the same time I obviously can't wait until Oct. to make a decision either. Suggestions?
