Matrox video cards, at least from the old Millennium onwards, have always had a very good 2D video signal 👍
I would say that in 2D, at least for the image quality, in the pc-home environment, they were sovereign (apart from the VESA compatibility for DOS games where S3 and CirrusLogic were further ahead 😅)
The pain points have always been in 3D, where Matrox has never shone, remaining in the great sea of mediocrity, first behind PowerVR and 3dfx, then nVdia and ATI (absorbed by AMD).
Moral of the story: Parhelia P650 / 750 will surely guarantee you excellent 2D quality and will be something to try in 3D without expecting great results in terms of frames or 3D effects (let's say something to try out of pure passion and to gain experience) 😉
Personally apart from having a max build for the period of my interest, I like to put together builds to experiment 😁
