If you are not up with the latest and greatest chipset currently available, you would be missing the KT133A. I originally thought it was not even going to qualify as a stop-gap between the KT133 and the up-and-coming DDR chipsets, but quite frankly it has shown us an upgrade path that has given us near-DDR performance using our "old" SDRam sticks. Here are our two previous reviews of the ABIT KT7A and EPoX 8KTA3 if you want a bit more depth than what we are going to cover here. This shootout will serve as a quick look at the features and performance of these two boards. I highly suggest you read up on the KT133A chipset if you are not familiar with its shining OC performance.
