Hey guys the questions says it all really; I would also like to OC with this mobo and can you please keep the price below £75
For best results you will want a 990X/990FX based motherboard.
Here is the list: https://uk.pcpartpicker.com/parts/motherboard/#c=17,18&sort=a7
I would recommend the Gigabyte GA-990FXA-UD3 or ASUS M5A99FX PRO R2.0. They are a bit over budget, but worth the money is you want to do some real overclocking.
If the budget is really that strict, go with the Gigabyte GA-970-UD3P or ASUS M5A97. These are the only 2 970 chipset motherboards I can recommend.
The ASUS M5A97 is currently in my build list; but it can't do Crossfire properly... the performance stays the same with a second gpu or even goes down!
What CPU do you have?
I have the FX-8350; Here's my build : http://uk.pcpartpicker.com/user/Tahab_1/saved/8Vx9TW
I also changed the motherboard and I'm just going to change the PSU and that'll be the final build
