The question is that Can i download GTA V and play the same game at other computer at the same time? Will my download stop or no?
Yes, you can do this. You can log in on both devices and play games on one while you download on the other (as long as you aren't simultaneously playing games on both).
Bear in mind that if both devices are on the same network, the download may cause connectivity issues with an online game you play at the same time, such as lag.
