Preparing for a new system

for video cards the ati cards for awhile have had multi monitor support. with most of the new ati cards you can run up to 6 monitors with the right cables. most times with two monitors most new cards have two hdmi headers for two monitor set up.
some people also buy new cpu with the built in gpu and use the onboard video for non gaming window. I would look at some of the toms hardware builds for the last year or two too see if you need a performace type rig if your a heavy gamer or video editor or if a 800-1200 rig with a standard intel cpu or amd would work. For wifi I would look at the new ciso 2 band units..do botjh 2.4 and 5g and get a two band card or usb stick. I would see in your house what band would work better. if your like me that lives in large condo the 2.4 band is clogged with other people wifi. and portable phones. if there a lot of distance between the router and your new computer i would also look into getting a high power usb card and base. in the us there sold as 600mw devices. they just have a more powerful radio in them for longer distance.
