I have a serious problem with my new Radeon HD 5870 for mac. While playing graphics intensive games like Starcraft 2, the screen will flicker or go into a hard freeze with either vertical grey lines or a blank screen.
Can anyone suggest any solutions?
My system detail as follows:
Mac Pro (early 2009)
Processor 2 x 2.26 GHz Quad-Core Intel Xeon
Memory 8 GB 1066 MHz DDR3 ECC
Graphics ATI Radeon HD 5870 1024 MB
Software OS X 10.8.3 (12D78)
