Since it will be mostly for gaming so I need like windows 7,8 or is linux ok for gaming?Do I need to buy windows 7 or 8 for gaming?also first time I will boot up pc will it work withought operating system?
Linux does have some games that will work with it but as mentioned most games are designed to run in windows. If you do not have the $ to purchase windows - you can download a copy from digital river (MS's authorized digital download source) and use that to install without activating using a product key and use it for 30 days as a trial (doing this allows you the time to save up to purchase and then you just enter the code after purchase and activate - so no need to reinstall and no loss of data by doing it this way.
Also Newegg currently has a $20 off special for windows 8.1 using code EMCYTZT5744 it is $79.99 including shipping. ( Deals Expire at
