I have recently just built a new pc desktop and everything has gone superb my specs:
Bitfenix Colossus case
MSI Z77A-G45 Motherboard
i7-3770k cpu with Hydro H80 liquid cooler
2x4Gb corsair vengeance ram Blue
750 watt OCZ 80+ Bronze psu
Everything went excellent until i bought 2x Asus radeon 6870 GDDR5 graphics cards, These have to be the worst crossfire compatible cards ive ever had i can't even get crysis 2 to run smooth on low settings ive tried numerous drivers etc and its just not working. I'm so annoyed ive had them 3 days and i just cant play anything with them, so the only option i have is to sell them and get another card.
So could anyone suggest a decent card that can outperform 2x 6870 cards but also not be more than my pc put together lol.
