Hi guys, I want to upgrade my pc but its old, I talk about E5200 g31m-s2l 4GB OF RAM nvidia 8500gt and upgraded psu corsair cx500. I upgraded my psu for one reason and that is to upgrade my GPU, I am looking for something like R9 270x GTX 760 etc. My problem is that will I have performance loss cause of my cpu i know its an old one but it performs well. What do you suggest me to do?
