[SOLVED] Pcie 3 card on PCI2

[sa.ceggm]

Hello.
Am willing to run an PCIe 3 graphic card on a PCIe 2. The seller said that the card won't work 100% it won't give its full potential so i want to know how good will the card work. Will it lose like 20%-30? Thank you

Full specs of your pc and model name of graphics card in question.

it will work no problem assuming your psu meets the power requirements of the card.
pci-e2 and 3 are 100% compatible.

pci-e3 has x2 the bandwidth of pci-e 2 but considering most gpu's wont get close to maxing out pci-e2 so theres no way your gonna lose 20-30%
you may lose 1-3% max due to optimizations made to the newer standards I/O. but thats it unless your running titans or 2070+

No loss in performance:

Impact of PCI-E Speed on Gaming Performance

Many hardware sites have shown in the past that video cards do not show any performance decrease by running in x8 mode and cannot utilize the larger bandwidth provided by the latest Gen3 specification. However, video cards are getting faster and faster so we felt it this is still true. Also...

Also, PCI-E is backwards compatible. You should be fine.
