My friend wanted a low budget PC, I got him the above combination.
Would it be possible to unlock 3 cores considering the motherboard, on stock cooling ?
Depends on the processor. If the cores are stable then yes, otherwise not.
What will be the main uses of the rig?
I'm asking because of the fact that APU alternatives can be suggested at the same price.
already bought the components or asking for suggestion ???
if the later then create a new thread for PC buying
He already bought them. A more definitive question would be - what is approximate TDP at 3 cores unlocked ?
