Quite simply..... Is an PCI 10/100 Ethernet Card better than the ones built into mobo?
My PC can be slow at downloads and web pages are a little slower to view. However, I use my daughters PC which has PCI Ethernet and it is quicker.... and her PC has a lesser spec than mine in all aspects.
I understand what your saying but it seems very strange as to why 2 PC's using the same router have differing download speeds (tested each against each other at the same time for the same download) and yet the PC with the lesser RAM, 50% less CPU Speed, Smaller HDD, Naffer DVD, CD ROM etc etc .....wins hands down. Thanks Chegs anyway.
