A week ago, I posted an article about AMD's new power house CPUs being available in stores; however, at that time there were no motherboards that officially supported these CPUs. Due to their high clock frequencies, the CPUs needs a lot of power, and not all motherboards are able to deliver that much. Two motherboard manufacturers are willing to put their neck on the line, and have stated that some of their motherboards support the two new CPUs. Gigabyte's GA-990FXA-UD3 (rev. 4.0) and GA-990FXA-UD7 (rev. 3.0) are capable of delivering the required power to the CPUs, and that is without a BIOS update. ASrock's 990FX Extreme9 motherboard will also support the new CPUs, but it requires you to flash the BIOS to the new BIOS P1.40.
If you do so happen to have one of the motherboards listed above and a FX-9590, then beware of one thing. The CPU has a 220 watt TDP, so it will require some high end cooling to keep it within the safe temperature range when put under stress. Reviews do state that the CPU never uses that many watts, but still uses a lot more than other AMD CPUs.
