Ok so I upgraded the new MP to 10.7.5 and installed a GT 430 I had laying around to go with the 4870 thats in it 4870 in slot 1 GT 430 in slot 2 both set as 8x. Main monitor in the 4870 secondary in the 430. I fire up cinebench to see how that effected the 4870. Cinebench doesn't even offer to test the 4870 and only bring up the 430. I run the test expecting the the low score that the 430 has always given me and it beats the 4870. It shouldn't be doing that at all.. Whats up?
