I guess that depends on what you mean by "too slow". What card is the low tier GPU? A Nvidia Tesla? I've always been under the assumption that when running two cards in parallel the faster card will almost always slow down to the speed of the card with the most memory, though the only reference I have is from using Nvidia SLI with two 8800s almost a decade ago. I could also be completely and utterly wrong, would love to hear from anyone in the field of GPU architecture or around it for some clarification though :)
