Good evening everyone, I need advice regarding my upgrade. Currently have two Mac pro's both (2010's). One 2.8 quadcore (single core), and the other one is 2.4 (dual CPU's). I plan on upgrading the the 2.4 dual tray to 3.46 six core's. Regarding which motherboard to use between both computers. Stay with the motherboard that the (dual Cpu's 2.4 originally, or does the 2.8 single core motherboard have an edge, since a faster CPU is in it ? Also can someone direct me to the firmware update, I forgot which one?, thanks.
