I have just recently redone my pc and bought all new parts except my 5770 which i kept. Ive built it especially to play biowares new game swtor when it releases. Im now debating wether to get a 2nd card and dual sli or just get 1 better card. my spec is: i7 2600k-corsair vengeance 8gb 1866-antec high current gamer 900w-asus sabertooth p67. I dont mind the extra electric costs if dual cards give me better performance over a single card, and my board supports ati and gtx cards. I have about £200 to spend
