Hi Guys! I have an old Dell Optiplex GX620. It's runs DDR2 and Windows XP... I'm looking for an upgrade to either windows 7 or Windows 10. I'm building this computer for DayZ Standalone and maybe Asseto Corsa. I'm going for a cheap budget of around $200. Does anyone have the knowledge to make me a list for MotherBoard, CPU, Graphics Card, And DDR3 ram for in my budget. Thankyou!
