I was able to OC the core on my 4670 from 750 to 850 without a sweat--I went to about 865 before I lost patience with it, and stopped bothering to OC it more. So if they used the same core in the 4650, only clocked lower, you should be able to get a decent OC on the core for the most part (though it will not be a sure thing). I'm pretty sure they used the same cores with the 4650 and 4670--they both have the same number of SP's and same bit interface, only the gpu clock speed is different, and the 4650 uses DDR2 as opposed to GDDR3. But to be honest, the only thing I got out of a 100MHz OC on the core was maybe 500 more points in 3dmark and 2-4 more fps in crysis (depending on the level and what was going on during the game).
when it won't be your primary card anymore...I'm sure there's some sort of volt mod for the 4600 series cards, but it seems like these cards aren't hugely popular, there isn't much aftermarket support for them (vmods, coolers, etc.) yet. So I'm not sure.
Regarding the DDR2 issue and overclocking--the performance difference between DDR2 and GDDR3 is fairly big with current cards and games as they utilize large amounts of textures at a time--so the extra bandwidth from the GDDR3 would be a huge step up. But to say there's no point in overclocking DDR2 is just like saying there's no point in overclocking at all--any increase will yield improvements.
