Can someone explain in detail how both works? Let's say I've got a pc with an i3 6100, so its gpu should be HD 530. So what happens if I were to place a GT 730 into the pc which supposedly slower than HD 530 (Based on a benchmark site, link below). Would I have stupidly downgraded my specs and wasted my money?
