lol I guess if your not a hardware specialist but when you look at the statistics of an apu and what it sacrifices compared to a dedicated cpu with a dedicated gpu its not an under estimation at all
the ps4 is based on a custom 7870 design I believe? Or am i confusing the xbone? Either way, thats the hardware the ps4 is stuck with, The standard 7870 is somewhere between a 660 and a 660ti. His pc is on par or slightly better than (just in terms of the GPUthe CPU leaves it in the dust)... but if he was going to buy a ps4? He could use that money and buy a new GPU for the price of the ps4 and put it safely in its place, daring it to try to stand up to the power of pc's again 😉
His cpu is by far more powerfull and his gpu is slightly better so yes it will be ahead and if he feels like buying a ps4 buy a 770 instead and be way ahead of the ps4 in every terms
