do games still treat them the same as sli and crossfire? I know that they are dual GPU's but I didn't think they had the same problems as SLI. IF that is the case the 7970 is not considered crossfire is it?
Dual GPU cards are treated as two GPUs in SLI or Crossfire, they are simply both situated on one card rather than two cards. You get similar issues over whether games or drivers work properly with them. If you don't want to worry about those problems, the 7970 is the best single GPU card you can get right now. Nvidia is preparing to launch their new 600 series cards, but those are still at least a couple of months away. Whether or not you want to wait is up to you.
