ECS G31T-M Review
ECS has released the ECS G31T-M as affordable Core 2 Duo motherboard which supports the latest Quad-Core and 1333 FSB CPUs at an affordable price of less than $75. In our testing we saw that performance is on par with much more expensive high-end motherboards. The integrated Intel VGA is also a nice addition because you don't have to buy a video card for your office machine or can use it to play back video in a Media PC.
