Well, I bought the R4870 from sapphire , the next day two acceleros S1 rev 2 , the temps went magically down , I was so happy , but still those driver issues pissed me a bit off but still I benched a bit and allso played Crysis and Devil May Cry 4, still the drivers Installation and uninstalation process after a couple of tries killed my OS [ BSOD fest ] , a format helped until I started to install the drivers again. There simply weren't drivers that worked for me in benchmarks and Games so I stayed with the 8.7 beta and one lovely day one of the R4870 died , noticed it in GPU-Z , just one GPU , tried that R4870 alone, no post ... VGA dead , the temps on core were good VRM's were cooled enough [ never went over 70 ] , RAMSinks allso. The cards were OCed to 775 / 1000 Still the card died. I returned the stock cooler on it, plugged out the second card and returned it to the shop got refund and bought another card. As I said before, maybe there is a magic behind the driver installation of ATI cards which I didn't follow.

But I still think that the R4 series is one big step forward , it just lacks propper driver support, I had issues with every single driver I tried from Omegas to DNA's to official or beta drivers. Now my GTX worked like a charm, installed one drivers OC'd it never looked back, If this happend to me with the R4870's I'd stay with them.
