ECS A770M-A Review
The A770M-A is an entry level AMD 7 series (770/790X/790FX) ATX size motherboard for the Spider platform (when paired with a Phenom CPU and ATI 3800 series graphics card). Upon first glance, the layout of the board looks promising. It has support for the Quad Core Phenom CPU as well as Dual and Single Core AM2 CPUs, so current AM2 users have an easy upgrade path to the Spider platform that should not break the bank all at once. The rear of the board is standard fare with no obstructions on the back.
