Asus has two boards with the new AMD790FX/SB600 combination. Both of these boards are practically the same, with the only difference being that Deluxe/WiFi-AP has an integrated WiFi (as you could guess from the name), and there's an interesting cooling system for the memory, as well. We wrote about the M3A32-MVP Deluxe here.
As mentioned, M3A32-MVP Deluxe/WiFi-AP comes with so-called Cool Mempipe technology, and according to Asus, it can lower your memory temperature to up to 10 C. Both boards support upcoming AMD AM2+ Phenom Quad-Core processors and Dual-Channel DDR2 1066, 800 and 667. As you can see from the picture below, both boards feature four PCI Express x16 2.0 slots with ATI CrossFireX support, and two plain PCI slots.
As for the other specifications, the board also comes with six USB 2.0, eSata, Firewire and LAN port. We will have to wait until the next month for more info on the new Cool Mempipe system; but that innovation, along with WiFi, might be the key selling points for Asus.
