Im planning to build this kind of setup this month. I just have questions about the APU and the GPU. Do i still need to install Drivers for the integrated gpu? Do i still need to disable the intergrated gpu? thx in advance...
No, you don't have to disable the on-die GPU or install its drivers since you seem to infer you will be using the R7-250 as a stand alone discrete card. Just remember which video port to plug in the monitor ;-)
