HIS just released a HIS Radeon HD 6950 with 1GB GDDR5 launched, pretty interesting as the reference models all came with 2 GB. It might shave off a little extra money as 1 GB gDDR5 kight cost 40 USD alone.
The card uses a much smaller than reference custom PCB and features a custom cooling solution with a large fan located in the middle of the card. The card has a 800MHz core and the 1GB GDDR5 is clocked at 5000MHz. Outputs include dual-DVI, HDMI and dual Mini-DisplayPort.
Pricing is unknown, but this release is interesting as it might try to fight off with NVIDIA's upcoming GeForce GTX 560 Ti. Photo below, click the thumbnail.
