Search for a future proof motherboard

I really need a new motherboard for my computer.

Thing is though it also means I'll need a new CPU. I've had a look around and found some okay ones but I have no idea if I'm getting the best deal because there are so many different motherboards and CPU's. 


If someone could help me find a cheap'ish' motherboard that'll last me and is going to be good for upgrading other parts in the future I will forever be in your favour.
