I am trying to set up a gaming computer I need some help. I have a Asus P5E3 deluxe Mb, 2) HD3870X2 and 1000 ps . I am trying to pick out a chip and memory this is where I need help. I am looking at Q6700 or Q9300? And what speed of DDR3 should get? I just had a very bad experience trying to get the 2) 3870X2 to work in crossfire on a M3A32-MVP + Phenom 9600 + 4 gb. The master card work good, but when I install the second card I have to removed the video cable from the master and switch to the slave card. In Device manger I only see one card. I have try 2) M3A32-MVP and 3) 3870X2 and I spoke too AMD, ATI & Asus and they all tell me that it should work but it does not. I also try the new drivers I try everything.So as of today I and going to Intell and I and selling my AMD setup on Ebay. Please give me the info so I can just play games and not spend 4 weeks trying to set up 2 video cards. I am new to Intell I have always used AMD for the past 10+ years. Thanks for the help.
