is buying a ps5 (not sure which one as of yet but prolly a pro) worth it for playing gta 6? ready description plsss

so i’m planning on getting a ps5 pro. i’m not that well off so i didn’t get it before. but now i plan on getting one in august or december but one of the two (since black friday sale etc ykwim). i shared this news with few of my friends and some of them said not to get it as ps6 would come sometime soon. although i dont think so but i still wanna know. cus i cant buy ps5 this year and again buy ps6 2 years later. so is getting a ps5 pro worth it now? also i plan on playing gta 6 and i heard it will give 30 fps so are 30 fps playable? or are they good for a game like gta 6? although i intend to play cod as well and fifa and uncharted but primarily i would play gta 6. so pls give opinions
