Go for H97 board with 4790, or Z97 if you decide in favour for 4790K, because Z board allows you OC. Also, think about M.2 connector, it is faster connection for SSD, you can buy Samsung SM951 with incredibly fast write/read speeds (2100 read and 1500 write, which is about 3x faster than Sata 6GB/s SSD). If you wanna save on motherboard, try something from older sockets, Z/H87, tehere are some good deals and those boards support 4790.
