I'm trying to decide what should I order. Both are in similar price but MSI 720 is equipped with DDR5 5000mhz, 790mhz clock speed while MSI Gt730 OC memory speed is 1800mhz but its processing unit is clicked at 1006mhz. Which one would be better? They're closing my budget atm. I'm gonna buy R9 but till then I need to have just any gpu.
