Compatibility between specific MB, CPU and Grafic Card

[FilipeLopes]

Hello,
Im quering about compatibility between specific MB, CPU and Grafic Card.
1. MB with 3.0 PCie Expansion slot;
2. CPU 2nd Generaton Core i7 processor;
3. Grafic Nvidia 3.0 PCie card.
The MB says in its Notes: "PCIe 3.0 speed is supported by Intel® 3rd generation Core™ processors."
The question is: Is the Nvidia 3.0 PCie Grafic Card compatible with the 2nd generation CPU? My question comes because of the description in the MB notes, since it says that the PCIe 3.0 slot is only supported by a 3rd generation Core processor and Im choosing a 2nd generation Core.
Does this means that the PCie 3.0 speed Nvidia card wont be supported at all or will just run at 2.0 speed?
Thank you in advance to all that can help me.

yes pcie 3.0 is backwards compatible. pcie 3.0 speeds will be supported if you get the newer processor but you should not be worried about that
