im thinking about get a gtx 650 ti boost, and i heard that running a running pci-e 3.0 card on a pci-e x16 slot, the card wont be able to run at its full ability, i was wondering how much of a performance drop would that be? and would it still be worth getting?

it will run at the max the pci-e slot permit and yes it will not run at full capacity could be up to 25 and 50 % of the max card could give .

Those are 2 separate specs. PCIE-3.0 slots are x16. Do you mean your running a 3.0 card on a 2.0 slot? 3.0 and 2.0 both operate on x16 slots.

None. The gtx 650 ti boost does not max out even a single PCIe 2.0 slot configured in x16 mode. You can use it in such configuration with no measurable performance drop at all.

I run my 7950 which is a PCI-E 3.0 card on a 2.0 slot and i have also tried it in my other pc with a 3.0 slot. I oculdn't tell the difference but in theory the 2.0 is slower
