Hey I currently have the amd A8-3875k cpu with the FM1 socket, so whats the best cpu I can upgrade to? P.S. money is not a problem
you've got the best cpu on the FM1 socket. so you'll need to replace the motherboard too...
with AMD jumping to an am3+ motherboard like the m5a97 R2.0 and an fx8320/8350 would be a nice step up (for about $250).
If you want to stay with an APU you'll probably want to go to FM2+ motherboard which will open the door to Kaveri which is coming out in the next 2 months. Then you'll sit on your cash till Kaveri comes out.
On intel, getting an i5-4670k on a z87 motherboard would probably run you $350-$400...
and if you really want to go nuts you can get a 6 core i7-4930k on a LGA 2011 motherboard... spend about $800 if you go nuts and get one of the ROG boards.
