Good gaming computer under 1000 dollars with no lag on minecraft day z or skyrim?

Looking to buy one not build one please just give me a link to a computer that would have no lag at all on theses games and the minecraft is on a server with about 1000 people any advice

Added (1). Oh and I prefer desktop computer

I laugh when i read questions like yours Minecraft can be played on the $35 Raspberry Pi with only 512 megbytes of ram in it. Do some research into Free Linux operating system

The computer you will be buying will have W8 installed on it not a good choice of operating system it's locked down and will only install and run software that's got the M$ UEFI secure boot digital signature, You may find that your games won't run on W8. So check it out first, if they don't then your going to have to Jail break W8, Got to this website and learn windows is not the only computer operating system in the world
