The Xtreme Plus is not a one trick pony or a solution for a dedicated card. The compatibility list for this piece of hardware stretches back to the HD 3850 on the AMD side and back to the 9800GTX on the NVIDIA side. The Xtreme Plus is a universal design with kits designed for each card available so you are not paying for parts you do not need and are guaranteed the correct parts kit to get it installed on your hardware. Not all video cards are covered in the compatibility listing, but the single GPU heavy hitters from both camps are included.
