Techpowerup published some information about the upcoming ASUS M4A88TD-EVO / USB3. This is a new AMD 880G chipset based motherboard, it's expected to be available for less than $150 and will be available with or without USB 3.0 support. Full details over here.
ASUS is readying one of its first motherboards based on the AMD 880G chipset, the M4A88TD-V EVO / USB3. This model comes in two variants, with or without USB 3.0 support, designated with the -USB3 suffix in the model name. It is a socket AM3 motherboard, supporting the upcoming line of Phenom II X6 and Phenom II X4 T series processors. The CPU socket is powered by a 10-phase VRM, it is wired to four DDR3 DIMM slots for dual-channel memory. Even as ATI CrossFire is not part of the 880G's feature-set since it won't support an external PCI-Express lane switch like the 890GX, ASUS found a way around and provided a second PCI-Express x16 slot, only that this one is electrical PCI-Express 1.1 x4, wired to the SB800 southbridge chip.
