Curious - PCI-e 1.0 and 2.0 compatibility Tags: Graphics Cards GPUs Compatibility PCI Express Graphics Last response: April 17, 2009 7:15 PM in Graphics & Displays Share Bluescreendeath a b U Graphics card April 17, 2009 3:22:04 PM Ok, so I know they're backwards and forwards compatible...but wow, they look very very different. The PCI-e 1.0 only uses the small front end section of the GPU, while PCI-e 2.0s use mostly the entire GPU section. (GPU section as in the lock-in part with the gold/copper strips) Wouldn't there be a structural stability issue, since you're distributing the weight of a rather weighty GPU on that small portion? Personally I find it hard even picturing it...

The cards that are mounted in the x1 slots are really really light, so it shouldn't be a problem.
