    The Radeon HD 3000 and HD 4000 series

    My first good Ati cards were a 2nd hand Sapphire HD3870 (PCIe) and a third hand Sapphire HD3850 (AGP). As they are made using a 55 nm process they are comparable to the nVidia Geforce GT200 series, as can my son's HD 4870 -a lucky dustbin find. My HD 4770 is even made on a 40 nm process, like the Fermi generation. Unfortunately the support for these fine cards in the latest OS-es is lacking, amongst others due to the lack of proper OpenCL support. We will miss the fine DP performance they offered.

    I hope the 6000 series support does not drop off too soon as well. These ATI cards are steady work horses despite no longer being up to much graphically in comparison to newer models.
