I was reading recently that perhaps my motherboard could be bottlenecking my system as a whole. As my graphics card is in a PCI-E 2.0 slot instead of a 3.0 slot. Additionally, I am wondering if my cpu is getting enough power. Though I've looked up the ratings for power consumption, I've found a number of mixed opinions. Finally, my motherboard has "Dual Channel Memory Architecture" does that mean that I need to have 2 sticks of RAM in it to fully utilize my hardware?
