Hardware-One has posted a review which compare Creative´s GeForce2 GTS to 3dfx´s Voodoo 5 5500 AGP card. Here a quote:
Go right along and enable 2X FSAA for games like Need for Speed and flight simulations! For now the cards are only good for 2X FSAA, and arguably 3dfx´s implementation looks marginally better than NVIDIA´s. Just marginally and not anything to kill for.Read more
Everything else about 3dfx´s superior 4X FSAA and fanciful games that will put NVIDIA´s NSR and T&L engines to good use, are just unappreciable features at the moment. The former does not have the firepower to deliver it and the latter does not have the software to support it.
