those instructions are only missing on very early athlon64s. they certainly have nothing to do with SSE4 at all. if windows 8.1 didn't support that, there would be a massive list of cpus it wouldn't work on.
What windows 7 to buy ?

I suggest that you look at this processor (which is the one in my laptop), and compare the additional instructions with the 6000+ and you'll find that it doesn't support prefetchW (you'll also see that PrefetchW is listed as an additional instruction for SSE4A) so any attempt to install the 64-bit version of windows 8.1 would result in getting a single finger salute from the installer after it finds out that the processor isn't compatible which is why I stated that I was limited to the 32-bit version as it doesn't require those additional instructions (I also don't want to have two of the games I own being discarded because they don't work or do but with illegible text).

8.1 breaks Skyrim, at least partially, if reports on the Steam forum is anything to go by
OP wants Windows 7. His choice, mine too.

i've looked at that page you've linked to and i have no idea how you've come to that conclusion.
it looks supported to me. having said that, a bit of further googling suggests that even if CPUs support the necessary instructions, sometimes a motherboard bios does not.the reason i mentioned SSE4 isn't necessary is because there are a whole bunch of intel cpus which i know don't have it but run windows 8.1 x64 just fine. look at conroe core2duos or kentsfield quads (circa 2006/2007). SSE4.1 only got introduced with wolfdale/yorkfield.
anyway, if you don't want to run 8.1 for other reasons, all this is a bit moot. :/
