ok so i set up some new stuff for you here https://************.com/p/1LJdb
here is break down of what and why...
CPU: that i5 is slightly outdated. you can still get a good Intel cpu without upgrading to i7 so i chose the 4670k ... great for gaming. i assume thats what you fancy.
RAM: you just need 8 gigs for your setup period. its doesn't really matter what brand but i'm a fan of kingston. i threw in 1600 mhz 8 gigs dual channel.
MOBO: intel corporation...lol. the one i threw in should do the trick. pretty decently priced and very featured.
~ your storage unit is fine and SSD's are really just extra cash..
