techPowerUp posted a review on the Diamond HD 3650 1024 MB DDR2
Diamond's latest HD 3650 card features a huge video memory of 1 GB, but uses only slow DDR2. For media PC systems an extra HDMI output has been added which natively supports HDCP and audio. We run this card through our benchmarks and check whether the extra memory can make a performance difference.Diamond HD 3650 1024 MB DDR2 Review
