techPowerUp posted a review on the MSI R5670-PMD1G Radeon HD 5670 1 GB

MSI's new R5670-PMD1G is one of the few HD 5670 cards that come with 1 GB of video memory, as opposed to 512 MB on most other designs. This review will answer whether there is any point in 1 GB of memory on a card like the HD 5670 or if 512 MB is enough.
