I read the facts page and I have a question. I honestly do not think I will get to use the step-up(nothing new released within 90days) so it may be a moot point, but can the EVGA GTX 280 01G-P3-1282-AR be used in the step-up or do i have to use the base one. The list shows the base gtx 280. They are on sale and only have a $10 difference between the two so I would just go for the 1282 version with the 621 clock. Thanks for the help with a noob to the evga graphic card world.
