I found my ASUS A8N-SLI Premium, which was my second OSx86 board at all, after a Socket 754 board. After several Athlon 64's I got an Opteron 185 and used 10.5.8 stable at 3 GHz overclocked. I never had to reinstall Leopard because it worked so well.
Now I've reworked this board and it works so well as before, with the same 10.5.8 installation. So I want to ask, what is possible after about 7 years? The Opteron 185 has no SSE4, I read Sierra will be the last one, but I also read of High Sierra. Is there a method to get my good old Radeon HD2600XT working in never versions of OSx86? It's able to 'overclock' monitors in Leopard, my 1600x1200 HP L2035 allows 2048x1536, my LG 3D TV 2560x1440 or 2560x1600.
Ups, wanted to write in compability check. I hate writing on smartphones. Please move the thread.
