I think u will be able to play ur CPU is fine as well as ur Ram and the GPU I ran GTAV on a GT610 its the worst GPU ever . you will be able to play but u will not be able to enjoy the game because ur GPU will be bottlenecking ur PSU.
Advice :- Change ur GPU that's it . I'll say go for a 750ti and if u have more budget go for 1050 its great I use it I know . U can play all AAA titles without even thinking will it run in ur rig.
