PCIE 1 and 2.0 Compatability

[NoEcho]

Lightning offended my radeon x1900. Now it hates one little something that happens every so often but only when it's a 3d sort of something. I cannot game.

My motherboard is a 939Dual-Sata2 and that means PCIE 1.0. My question is: are PCIE 1 and 2 cards cross-compatible? Am I limited by this mobo to PCIE version 1 only?

PCI-E 2.0 cards are backwards compatible with PCI-E 1.0 motherboards and vice versa.

However there are some reports of PCI-E 2.0 video cards not working with motherboard that have PCI-E 1.0a. Do some research if your motherboard has PCI-E 1.1 or PCI-E 1.0a.
