I vote for Visiontek.
Since Visiontek supplies Elsa, you can use any of the Elsa drivers or addons like ViVo module, after flashing the Bios. Comparing the Elsa and Visiontek cards, shows that the Visiontek card actually has "more" connectors on it for addons, and the construction quality looks to be much better with the Visiontek, compared to the Elsa. Other than that, (and price), both cards are identical in performance and image quality, which is the best of the GF2 GTS cards. Also, the Visiontek cards are the only ones made in the USA. Even some Elsa cards are made in a plant in Hungrey.
