We all have to suffer with strange graphics card names especially when it comes to NVIDIA products. Their partners choose all sorts of weird and wonderful naming conventions to distinguish their cards from their competitors that on first inspection, seem very similar indeed.
Gainward is of course the first company that springs to mind. Unless you have been forewarned could you tell the difference between a Golden Sample 750/XP and a Pro/650? or could you tell which cards out of NVIDIA's ever expanding range they actually are?
The latest incarnation from Abit however, dubbed the OTES is a bit easier to understand, assuming you read such sites as ourselves.
OTES stands for Outside Thermal Exhaust System.
