GTA 4 Disc or Digital

[ArcticSkeleton]

I don't think this has been asked before, but I own the Steam version of GTA 4 and it's horrible when it comes to stability, but I've been seeing people say that the disc version is better in stability, and how digital versions have this area of code that's broken, or something like that, Is any of this true? And if I wanted to play GTA 4 with over 20FPS should I get the disc version?

I already have a decent PC with a i7 processor, but with an awful graphics card, if that helps.

I'm pretty sure the people who say disc version is better in stability is wrong. If the Steam version lags on your PC, no doubt the disc version will too. They're the same, really. Except for the fact that the Steam version comes with the latest update included, and for disc you have to install it on your own.
