No, I won't need the SLI/Crossfire ready feature.
I will go for the Z87-A, if I can ensure 100% that my PCI sound card (EMU 1212m -which is a really "selective" card regarding IRQs) will get absolutely no conflicts.
From this tablehttp://i222.photobucket.com/albums/dd254/emu1616m/Z87-A_zps1e5c32f0.jpg
I read that the PCI slots will be sharing either with the SMBUS and Thermal Controller or the Intel PCH SATA controllers. Do you think that I won't get any problems?
(At Z87-K, there's a PCI slot shared with an *empty* PCIe slot.)
Should I trust these tables or is there a way to avoid probable conflicts?
