Only thing i hate about the 68xx series is you can only run 2 cards.
Same thing can be said for 460 and below.
PaliT GTX 460 1GB Sonic
It has a custom PCB design, uses one PCIe x16 connector, and is actually a full inch shorter than the reference card- a huge pro for SFF users.
Does the 560 use two power connectors?
