Hello I have this pc Acer Predator G3-605. It has i7 4790 non k and gtx 970 with 8 gb ram. I want to know if I can upgrade it with the Gainwar Geforce RTX 2070 card. Will I be able to put the card in my case on my Acer motherboard , do i need a better power supply (I thnk I have 500W) and do I need to have more ram? If I cant upgrade my pc with this card can you tell me some possible ways I can upgrade it. The PC is 5 years old now . Thank you .
