Can the hp envy h8 1534 support the AMD FX 8350 or any intel core i7 processors?



Proceed with caution, but you should only need a BIOS update to run an FX-8350 aka "Vishera". If you poke around HP's support site you will notice many machines with the angelica2 mainboard (same as yours) which are running the 8350 processors. I myself have an H8-1223 with the angelica2 that came with an 8150 and now has an 8350 happily purring under the hood.
