So is there PCI-E 2.0 and PCI-E 3.0 ? What are the differences,

also is there any size(height etc) differences between DDR3 and DDR5?

There are PCIe versions 1 to 4, version 4 is not yet available, versions 1 to 3 use the same connectors & are generally backwards compatible (on one machine I have a PCIe 3 graphics card in a PCIe 1 slot) - have a look here for more info https://en.wikipedia.org/wiki/PCI_Express (thank you google).

 

DDR3 v DDR5 - you can only be asking about graphics card memory as DDR 5 is not available for standard RAM usage. So the answer is that these are just memory types & so do not affect the size of anything (nor do they affect the compatibility of a graphics card with the motherboard).

The correct video RAM for a graphics card is already fitted to the card by the manufacturer.
