So i'm like helping a friend with a $1100 gaming rig. We initially settled for a i7-3770K, but due to budget constraints we are now looking very dearly at an i5-3550 
We are currently planning to use an Intel DH77EB mobo, but I was wondering if we could find a cheaper mobo, that has 4 RAM slots and USB 3.0 support (Intel/Asus/Gigabyte only).
Basically I have these 2 questions,
1. What is the main difference between H77 and B75 chipset motherboards?
2. Is it possible to perform that +4 speed bins OC that non-K edition chips support, on a H77 or B75 mobo, or is that only supported on z77 ones?
Here's the link to the planned build, http://www.tomshardware.com/forum/384959-31-gaming-build-1090-indian-rupees
Thanks in advance
