Quadro FX 570 and pcie slot question

[Slug]

I'm currently running 2 Quadro FX 570s in a core 2 quad pc (Dell T3400) driving 4 dvi displays. I can't seem to find the pcie generation of the cards or the mobo slots. I'm assuming all are gen 1.

My question: can I move the quadros to pcie gen 3 x4 electrical slots and get decent performance (well, for old cards anyway)? I want to move these to a low end skylake system.

Thanks

The new slots should be backwards compatible.

It's backwards compatible with all previous generations[1].

PCI Express 3.0 Base specification revision 3.0 was made available in November 2010, after multiple delays. In August 2007, PCI-SIG announced that PCI Express 3.0 would carry a bit rate of 8 gigatransfers per second (GT/s), and that it would be backward compatible with existing PCI Express implementations.
