Your 1st link just goes to an empty cart. The real cart will only be saved to your PC or account.
Your 2nd link is a pretty good machine for high settings at 1080p. I can't tell whether the specs for the LAN say 10/100/1000 or just 10/100. I see GB just ahead of the 10/100, so I assume it is 10/100/1000Mbps.
