I just bought the Visiontek after much research, and so far I haven't had any problems with it...although I haven't gotten to play with it much as I am still trying to get my RAID configuration to work. 🙁
All the employees at the local computer store where I purchased my card really loved it, so I would say that it is a very good card.
Yes, the Visiontek has VIVO by way of an adaptor. However, in their rush to get the product to market, they left out the adaptor and put in a coupon for the adaptor and a free t-shirt. No big deal though, as you can fill out an online form and you should get the adaptor in 6 weeks (I hope!)
