The Gigabyte board features the X38 chipset, which has support for Intel's upcoming 45nm Penryn CPUs, DDR2 and DDR3 RAM and all the other features I described in my previous post. The ASUS Striker Extreme has the NVIDIA 680i SLI chipset, which allows for SLI, possible support for Penryn CPUs and is a great overclocker. But as you can see, the X38 mobo is more feature packed so it's the way to go. Both will fit your card and processor, so it's not a problem if you get either. It's just that you'll have more upgrade options with an X38-based board.
