I've got a HD6850 I've just upgraded from. The 2nd hand price for this looks to be £20 - £30.
The HD6850. I know the price of my card, not yours, but mine is more powerful so I think you're being overcharged.What the 6850 is £30 or the 5970
Im pretty sure a gt 1030 would have better performance, and also more up to date drivers, for about £70-£80 if you look around and can afford that much.
The 5970 is considerably more powerful than a 6850, being essentially based on 2x slightly downclocked 5870 chips (where a single 5870 is slightly more powerful than a 6850)The HD6850. I know the price of my card, not yours, but mine is more powerful so I think you're being overcharged.
In games where Crossfire works the 5970 would be a decent amount quicker than a 1030.
However the 5970 is frankly ancient (and the last drivers for it were issued ~2 years ago).
For similar money used, you would be better off looking at any of the following:
AMD: 7850/7870/R7 260x/R9 270/R9 270X
NVIDIA: 660/660Ti/670/750Ti/760/950
which all perform at least similarly, but with the benefit of current drivers.

Would i be better adding extra £15 and getting a 1030, do i look at core clock speeds when looking for a GPU
Core clock is meaningless on its own.
Personally I wouldn't buy a 1030, but if that's all your budget allows, then it's really the only option buying new.
Worth bearing in mind however that most of the used cards I listed above perform considerably faster, with some of them being nearer in performance to a Geforce 1050.
I havent got a clue what to look for to determine what card is better than another
Hi all
Been offered a HD5970 for £50 but not sure what it will cope like at 1080p gaming on ETS2 mainly
Not expecting it to be mental performance for this price
Cheers
For £50 you should be looking at 7950's or 7970's.
I wouldn't bother with the 5970. Hot, power hungry, loud, crossfire dependant.
As said above. It's ancient. Driver support for this card stopped ages ago. It doesn't support anything over DX 10.1.
The fact that driver support stopped years ago and it needs crossfire profiles to run well it will be a waste of cash.
Save you money and by something more modern.
look for a gtx 670/680 if someone is after a quick sale
