Thanks for the reply
I considered 6600 because here, 6500 is not available
What is the difference between asus B150 PRO GAMING/AURA vs H170 pro gaming aside the chipset features
Go wIth the 6600 then. stay away from the 6400.
Aside from teh chipset features, the H170 pro gaming has 4 pcie x1 slots while the B150 PRO GAMING/AURA has two old school PCI slots and two pcie x1. That, and the h170 has DP, VGA, HDMI and DVI video outsw while teh b150 only VGA and HDMI.
EDIT: My suggestion from a bang for buck perspective is the MB in teh build i linked. Out of the two you listed, i would go with the h170 because the B150 chipset does not do RAID.
