    5890 can and thus will happen.

    Virtually all 5870 (850Mhz) can max out overdrive at 900. Most cards do around 920-935 @1.15V. It doesn't take a genius to figure out that better binning or 1.2V could get 950Mhz. But to stay within 225W, probably binning.

    Memory on 5870 (1200) overclocks to 1300. I doubt AMD will bother trying to source some rare uber high end GDDR5, since most of performance improvement is from core overclocking.

    Therefore, "5870 OC" is probably gonna be something like 950/1250 2GB (with overdrive headroom up to 1000). Despite +12% clock, performance probably only +5%... you know, diminishing returns.

    ===========

    if I recall correctly, 5870 is 4 phase, and 5850 is 3 phase. For 4890 (5 phase?), AMD made better than 4870 PCB.. maybe they'll reuse that idea..
