boring shit sia...come on 4890 and performance just not up on par leh...guess gonna skip this and go to nvidia this time,ati just starting to make thing worse again..
just because you can milk 4870 and 4800 series doesnt mean you just dry it out..it been too long edi,come out with new series and much more improvement la at least..20%?? come on...i guess a 4870 running at 850mhz core should equally more or less the same...

i doubt this can happen,but hey who know?but then if increment up to 20% of 4870 i dont think so it gonna even level with 285...
