Pci slot graphic colour code

Generally speaking, motherboards with multiple graphic card slots are labeled PCI-E_1, PCI-E_2, PCI-E_3 and so on. Numbering generally begins with the slot closest to the processor.

If you want more detail, it might help if you told us what motherboard you have.

Yes it is a HP (a6332.uk) and it looks like the picture. Is it only worth it to use the PCI-E slot (I only have a 17 inch monitor).
