I question the need for dual video cards - most of the time a single card is more cost effective unless you are looking for ultimate performance for this month (e.g. have money to burn). You can buy a new single card a couple of years from now and typically get better performance again than adding a second card unless you are at the very low end.

SSDs are nice but still expensive, and I leave my PC on 24x7, so a fast boot is rarely important. I'd suggest getting a 3 drive setup with 3x WD Black 2TB drives, run one as a boot drive, setup a RAID 0 for the other two, add a fourth for dedicated swap drive if it is in the budget.

Since you are talking audio, a high quality name brand power supply like PC Power and Cooling will help keep the noise out and be stable under load at it's rated power, where a cheap 875W won't really support it. Also consider a larger quieter fan setup and may be a sealed water cooler or total water cooling to quiet the whole system.
