I'm not extremely tech-oriented (as will soon become evident. )
Not that long ago, a computer salesperson told me that a graphics card requiring a PCIe X16 (?) **2.1** motherboard slot will "work just fine" in a PCIe X16 **2.0** slot. Is this true? ...Or would the card "fry"...or just under-perform?
What would result if a graphics card requiring a **3.0** PCIe X16 slot is plugged into a **2.0** PCIe X16 slot?
Any insights given will be greatly appreciated. Thanks!
