I have MacBook Pro 15 inch mid 2012 2.3ghz 4gig of ram and I do test geekbench my muti-core score is just 7000 but single-core is 3100. I don't understand why. I just upgrade hard-drive to two ssd raid. is the two ssd made lower score?? because I used to test it before my score is about 10200. now I have a little worry that my cpu doesn't working full performance .
