ATI Radeon HD 4000 Series discussion

[003]

I'm hoping that the added TMUs will help the sub-par AA performance that the 2900 and 3800 series suffered from.

Any word on that yet? I'm an admitted AA whore.

ATI does AA in the SPs, which have been increased to 480 on the HD4000 series for the 4870 variants, and they have also unlocked the shader speed from the core, so it is more like nvidia cards in that respect now, and hopefully, there will be a way to overclock the shader speeds, which will come at 1.05GHz, next to the 850MHz core.
