The GOG's version are different or are the same?

GOG doesn't have a D&D anthology collection that includes Baldur's Gate.

Sorry my fault, I miss the subject!

BD 1&2 from Atari collection are the same of the GOG version?

I have heard that folks have had problems with this and the digital version of it that were resolved with the GOG collection.

If you want a digital collection, I strongly suggest buying the deal. It's as cheap as it will ever get. However, if you're using your discs right now and it works for you, then feel free to keep using it.

I have the BG collection and IWD collection and both worked fine on my Windows 7 system. But DRM-free copies (no disc in the drive) and the ability to easily download and play made the GOG version very much worth it for me.

If you want to wait and try the games on the disc, just know that the D&D deal tends to come up every 6-12ish months.

Thanks for all the replies.
