Upgrading my comp need help

the main piece i'm looking at upgrading my mobo, cpu, and memory and i have a slight budget to do so to get the best gaming performance i can out of it, mainly play games like wow (into raiding at a high progression level), sc2, d3, and dota2 for now (if that info helps at all). not looking to oc seeing as i'm going to have to find help to update the bios and everything which means i have no idea what i am doing for the most part when it comes to ocing.

going to list and link my current parts.

i want to stick with ddr3 1600 1.5v memory.

i want to go with kingston memory since i've had nothing but good customer support from them but having to rma my current memory with them makes me think about looking else where.

feel free to ask me any questions if something doesn't seem right or i missed something.
