I have 2009 2x 2.26 quad 32 GB RAM GT120 driving two monitors I'll have usually two vms running via VMware fusion and most of the time they are under low load. I WILL have multiple Chrome windows open with many tabs in each. My boot drive is SSD with 20 GB free. Sometimes if I open few tabs with videos they will not render right, or video played will be choppy. What video adapter should I go with? I don't want to run extra power supply booster. I don't edit videos etc.
