Not much of a computer guy and i need some help.I have an AMD A4-5300 APU with built in AMD Radeon HD 7480D graphics and i was wondering if i'd be able to add a separate Graphics card to my computer to increase my fps in Cs Go. I currently get about 40-70 fps and im looking to get at least a constant 100 fps without spending over $250. Not sure if you need any more specifications of my PC. Let me know if you have any suggestions.
