I'd make a check list of the features on each of those. Much of it is hard to evaluate due to the marketing lingo. Ultimately, choose a brand with a good rep, get the features you want, at the price you want. Then hope you don't have bad luck and get a poor example due to poor quality control.
Are you planning on a new case? Those are ATX boards and won't fit in that HP micro-ATX case.
Asrock used to have a mediocre reputation, but seems to be more highly thought of in the last year or two. I'm not sure if they are still owned by Asus.
I'd at least check out Gigabyte motherboards.
Are you restricted to Amazon.uk as a source?
Even if you can't buy from Newegg, you might get some hints from the board reviews there, although many of the reviewers are either fanboys or dim bulbs.
Is the Gigabyte X79-UD5 LGA 2011 good for high end graphics gaming? And will it accept AMD as well as Intel CPUs?

What is your budget?
What will the PC be used for?
What do you want to "reuse"? Probably only going to be able to salvage the HDD and Optical from your current system.
What is your display setup?
Is it the same situation with modern CPUs as it was with Pentiums vs Athlons? If I remember right the Athlons were cheaper and faster? Is that still the same, that you're getting a better deal all round with AMD?

My suggestions for a 2011 build
SSD Newegg.com - Kingston HyperX 3K SH103S3/90G 2.5" 90GB SATA III MLC Internal Solid State Drive (SSD) (Stand-Alone Drive)
GPU Newegg.com - EVGA SuperClocked 012-P3-1573-KR GeForce GTX 570 HD w/Display-Port (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card
So, just slightly over budget, but definitely a nice rig.
