When we reviewed the ASUS Sabertooth 990FX motherboard several weeks ago, the planned launch date for AMD's new AM3+ compatible Bulldozer chips was September 19th. Finally on October 12th the chips began popping into online inventories everywhere. Unfortunately a slew of reviews published that same day gave the FX series Zambezi chips scathing remarks. Despite lackluster performance from the new FX processors, AM3+ does still have some benefits to offer AMD users, particularly if you're still on an older AM2+ board or utilizing nVidia SLI. If a $200 motherboard isn't in your budget, the ASUS M5A99X EVO we have for review today may be just your cup of tea.
