What do you mean by overcocked do you want to eat this in you dinner?
If you want to write overclocked then i say no because many new games need DirectX 11 and 4890 does not supports DirectX 11 but it is better then the both other cards
Correction- not only 4890 all 4000 series doesn't supports DirectX 11
"What do you mean by overcocked do you want to eat this in you dinner?" - it takes one to know one
and does it matter if it doesnt support DirectX 11
