Now this could be a dumb question, but I'm thinking of upgrading the graphics card in a system with only a PCIe v1 slot. Are PCIe v2 cards backwardly compatible with PCIe v1 mobos?

Yes in every case
Exactily. I'm running a Radeon 4870 on a P35 Motherboard just fine :)Quote:

I have been involved in IT from a young age as a hobby and professionally for 10 years. That was most certainly NOT a dumb question. You can never trust any kind of theory unless you test it or can find someone else who has :)Quote:

(For reference, my ULI chipset has a PCI-E 1.0 slot and works fine with ATI PCI-E 2.0 cards).
My antique ati 3200 based xfire board ran my 4850 with no problems ever.
