The best one is Msi 290x lightning but its expensive.
Second best one is Gygabyte 290x windforce
Then there is Msi 290x twin frozer.
Cheapest version I believe is from Asus it is 290x DirectCUII.
Try looking up those cards. In my region directCU is 500euro
Gygabyte and twin frozer are 560euro and Lightning one is 600.
