OCW has posted a comparison review between XGI Volari V8 versus Deltachrome S8
The Volari V8 certainly proved to be a very interesting piece of hardware. This card has pretty good performance for the average gamer as we can see and proved to be a worthy alternative to the Radeon 9550 and GeforceFX 5700 LE which are both in the same price range. Its performance seems to match the Radeon 9600/9600 Pro too.Read more
We did not mention about overclocking in the review. The Volari does have some overclocking potential though : we were able to clock the card from 300/300 to 395/390. As a result, we were able to reach a score of 3118 in 3D Mark 2003.
