Pro 3 has 2 6Gb SATA ports, Pro 4 has 4 (both have 4 SATA 3Gb ports); Pro 3 has 2 PCI slots, Pro 4 has 3; Pro 3 has 4+1 phase power, Pro 4 has 4+2; Pro 3 has 4 USB 2 rear panel ports, Pro 4 has 6; Pro 4 has an optical out, Pro 3 doesn't.
Just got a Pro 4 and a i5-3570K for $260 from Microcenter. Just got my GTX670 in, gonna put it all together this weekend.
