Hlsgsz :
1, without a doubt. GPU is way more immportant and those two CPUs game the same anyway.
I had a doubt .. if I go with (4x2) that is 8gb ram sticks .. in future if I want 16gb ram .. do I need to completely buy a new 16gb pair.. or can I an add another (4x2)ram-stick of the same brand nd model of the 8gb which I brought earlier ??
