Zona nisipurilor mişcătoare mainstream ne aduce astăzi pe bancul de teste o placă video GIGABYTE Radeon HD 5770 dotată cu 1GB de memorie GDDR5, GPU ATI Juniper pe 40nm, suportul nativ pentru DirectX 11. Enjoy the ride!
Practic avem în faţă un vârf de lance a celor de la ATI, Juniper şi implementarea sa sub forma plăcilor video Radeon HD 5770 fiind adresate în principal sectorului mainstream mai pe româneşte nici prea scump dar nici prea puternic, nici prea ieftin dar nici prea slab.
