U'r poisoning me 

thanks everyone that replies ...
hmm it seems that some said can some said cannot, i thought huntkey main selling point was cheap "true power" psu,not? how come other's branded "true power 550" can operate well(ati certified psu)

ps:i thinking can sell my 4850 n topup some money get a 4870 but now have to think twice

YES, our 1GB version will be ready around mid-Sep. Good for big monitors (22" and above).
Unable to tell at this moment. Our Gainward 4870 GS will be here next week, so it will take about 1 month for people to report in with scores. Many people (dealers and users) told us that Gainward Golden Sample models offer the best price/performance ratio. So big thanks to you all. 

PowerColor we dunno when will come, please ask the local distro. 

We do have comparison with HIS Turbo and Sapphire Toxic for our 4850 Golden Sample (see links below).

Hope that helps.
