Yes we can play GTA 5 in i5 laptops but laptop must reach requirements:
Minimum Windows 7 64 Bit
Minimum CPU I5 Minimum 4 cores
Minimum 8GB Of RAM
Also you need to include graphic card to run the GTA 5
NVIDIA GTX 660 2 GB OR AMD HD7870 2 GB(OR ABOVE)
Even though you have all these requirements you can’t play game in higher graphics must set all display and graphic settings in low to get some good FPS and smooth gaming experience. because frames win games.
