I have built myself an ultra low budget pc rig
Specs
Amd A4-6300
EMX-FM2+iCafe motherboard
160Gb Seagate
500Gb Western Digital Scorpio Black
Trigon Case and 600w PSU
Zeppelin 4Gb DDR3-1600
is my build compatible with XP?
look on amd web page under drivers see if there any chipset drivers for your mb. new cpu and mb can run the older os as long as there drivers for there hardware.
