Dear kenneth12129, i have the gtx 260, and in order for it to fit into my RAIDMAX Sagitta case, i had to dismantel the plastic pins holding my harddraive, then lower my harddrive into another socket..... making it fit!!! and it JUST fits!!!! by the skin of a hair!!! i'm not sure what the dimension differences are, but from my research, they are about the same.
hope this helps!
