ELSA is adding yet another top-notch choice to the list of cards worthy of costing nearly $300 dollars as it offers leading edge performance 3D performance. ELSA is offering the basics like a DVD player and some bundled demos but nothing spectacular over the other available DDR GeForce cards yet they are charging a slightly higher price.
I can't quite see a compelling reason to go out and buy the Erazor X² over the Leadtek WinFast GeForce DDR or the Outrageous 3D GeForce DDR board unless it is of importance to you to have the ELSA brand and support. Granted they supply a sturdy driver, but most of the companies are offering drivers based on the reference drivers from NVIDIA, so that isn't a very good reason either.
My final judgment on the Erazor X² is that it's an average DDR GeForce board at a high price. Unless the ELSA board is the only thing available in your area, I see no reason why you shouldn't go with the Leadtek or Absolute Multimedia solutions. My favorite GeForce DDR is still that Leadtek WinFast 256 DDR that offers a solid board, good software bundle, and is widely available all at a low price. You can't go wrong with any of the DDR solutions but why spend the extra $20?
