Placa de Vídeo até R$ 1500,00

[MytosBR]

Olá, tenho uma Radeon HD 6800 e tenho tido baixo fps em alguns jogos. Queria saber se devo comprar uma nova placa ou fazer um crossfire. Nao acho essa placa 6800 em lugar algum, e nao queria gastar mais de R$ 1000,00 mas posso gastar até R$ 1500,00.

Assassin's Creed IV quero rodar no máximo. Qual Placa devo Comprar?
