I have been looking into buying a new gaming computer because my current computer, an Acer AspireOne netbook runs Minecraft well, but bogs down when playing hi-rez games such as Runescape.
Costs around $800
at least a 15 inch screen
Very good with hi-rez games
Everything else really doesnt matter. I keep my laptop plugged in when playing because i dont use it anywhere except at my house. So thats pretty much it. If you need more info, I will be glad to share it.
