Best motherboard for i5-2500k for overclock around £100

Hi guys

You may have seen my previous thread when I was contemplating between AMD and Intel for my cpu.

I have since chosen to go with the i5-2500k

I would like some advice on the best motherboard, around £100 but can go higher, to get a decent overclock out of this CPU. I'm aiming for 4.5GHz but above that would be awesome.

I have no preference to manufacturer but I am a little sceptical of BioStar boards. If you can prove to me otherwise why I should go for a BioStar, then i'm all ears.

Along with being a good overclocker I am also looking for SLi and/or CrossFire capabilities both running at x16.

I will be using the system primarily for gaming, but also for some software development at some point.

Any links to go with the information you provide would be appreciated.

Thanks in advance
