Can I have an R9 290 on a AMD 760G Chipset?



Yeah, an 8320 will do it fine, maybe some slight bottlenecking in games that don't use many cores but it still shouldn't go below 60 fps. I have an overclocked 8350 and 290 myself
 


The 8320, for some reason, is not working. When I boot, I get nothing but a black screen.
 



The BIOS may not support the 8350 yet and may need updating. Put your old CPU back in and update the BIOS to the version that supports the 8320 if it exists. However I would reccomend upgrading to a newer motherboard. You will need to purchase new thermal paste
