the pc shops here are joke they have no idea about computer parts. they will sell you anything and say yes sir same same. I ask them for AMD cpu and motherboard they tried to sell me two different sockets types. they said yes yes AMD same same. Most of their stock is 3years old and they want to much for it. If you want the latest which is still 9month behind rest of world. they want 3times the price as it would be in USA. all the stores are own by same guys and all bought thru KSA. so you can't even ask them to get you what you want in.
only place i found is in the street behind sofitel called tornado computers he mainly sells gigabyte stuff and he knows about pcs
