You will Yes, DRAM itself is a 64 bit device, when you run DRAM in Dual channel it is used as a single 128bit device and can be up to 10-15% performance wise, tri channel operates as a 196 bit device and can pick up another 5-9 percent performance wise, true quad channel as on the X79 mobos runs the DRAM as a 256 bit device and performance increases even a little bit higher than tri-channel.
