wait i just noticed the gpu was intergrated. thats even worse. the mobo is ok. noting fancy. but the ram is very good. first look in the computer. see if you have a pci-e 16x slot. it's easy to find it. look on google images. if you find one. measure how much space you have in the tower. then find a good gpu. a good one is like an amd hd 7770. but first check the watts on your psu. buy the 7770. put it in the tower. it will work fine after that.
