|The Dell has a faster processor than the eMachines. The Dell also has a cooler (Heat wise) video card than the e-Machines because from my experience ATI cards produce less heat than Nvidia cards. |
For support I recommend the Dell because they will maintain the drivers\support page longer than eMachines will. I have had bad experiences with eMachines support due to lack of support for 5 year old computers.
If you want to save money you can find a used Pentium D computer for less than this and it will run any flash games.
Pentium 4s - The processors for the rest of us.
