e-machine is gateways “value” line. You get what you pay for.
Your monitor should work with any new computer should you want to keep it.
I suggest Microcenter or newegg.. Stick with the name brands. Staples, officemax, office depot all have huge sales going on. Some are even giving a trade in for your old working (well enough for them anyways) PC.
Both e-machine and Gateway are now owned by Acer.
