Just wanted to get a few expert opinions on my planned build before I make a mistake. Asrock Fatality 990fx,AMD FX-8150,4x4gb g skill ripjaws 1600 ram, 2 Radeon 6770's in crossfire, (with thhese components the scorpius platform is supposed to be unlocked), CM silent pro 600 modular, HAF 932 AMD special edition case, CM n520 cpu cooler, 60 gb ssd,1.5 tb w.digital mechanical, and other extras. One thing that I'm concerned with is the Asrock website listed all 6000 series cards EXCEPT the 6770 as crossfire ready and I wasnt sure if it was a mistake or if anyone had tried it just to make sure that it would x fire.I have an xtra 6770 now and I was going to save money and just get another but if it wont x fire I'll just get a triple fan Gigabyte 6870 and sell off the 6770 (which was never used on a previous build). If anyone can direct me on this I would appreciate it. I dont want to but I will switch to a sabertooth or 990fx-ud5 if necessary. Thank you
