I have been searching for a GTX280 card to SLI my single GTX280. But i can not find any for sale ? Did they stop that card ? I can still find cheap 260 cards. But no 280. If i understand SLI. I have to use another GTX280. I cant afford to upgrade to the 400 series. So if anyone has a good GTX280 card sitting around after upgrading to the 400 series. And you would like to pass it on. Please get in touch.
