So i decided to upgrade my gpu from r7 250 xfx core edition to a new gpu and my amd apu a8 6600k to a new apu. My motherboard suprts socket fm2+ and i have one pci-e x16 gen3.0 slot for new gpu. The preoblem is i don't know which gpu to buy and which cpu. My power suply is 500W and i have one 6pin conector. I need help for picking new parts.
