"Adobe Creative Cloud" is a proper noun, so no synonym. Same with Softonic, CNET, etc.
But "Adobe Dreamweaver, Google Web Designer, or Construct 3" are proper nouns. So "or" is a conjunction. So in the first sentence, after Adobe Dreamweaver, it's "or Construct 3": the "or" should be replaced with and or similar.
"Graphics Card: 128 MB of VRAM (256 MB recommended)". "Graphics Card" can be GraphicsGPUCard.
