It's very possible that GTA 5 would run... but at what cost. A bootable game isn't a good experience. You will get about 720p LOWEST 20-30fps (24 is considered the ABSOLUTE LOWEST FPS for a playable experience, and I question if it can even do that.) So yes you are going to be able to run it... but at that point it's not going to be worth the cost for a sub par experience.
