techPowerUp posted a review on the AMD ATI Radeon HD 4830 512M video card
Today AMD launches their new HD 4830 Series. The cards come with a reduced shader count of 640 and lower clocks to fit into the $100 to $150 segment. In our testing we saw amazing overclocking of over 30% which should bring the card much closee to more expensive solutions.AMD ATI Radeon HD 4830 512M Review
