I feel like I have gone back in time 20years. Matrox made it's name initially in the mid 90s with the Milleniumin which was capable of higher resolution / sharper displays. Later on in the CAD market (Matrox Impression add-on) they made another splash with 3D acceleration. Subsequently they tried to leverage that success with a marketing campaign based upon their cards being "professional grade".... with results that were short lived and cards from 3DFX and Diamond rose to prominence. The next cards was the Mystique (oft dubbed "Mistake") in that it had very poor 3D images and paled up against the Voddoo cards which were all the rage. Any perception of Matrox cards being superior or magnificent in any way in this day an age is merely remnant of reading those article in the mid to late 90s.
The last significant Matrox placed in the PC market was in the 90s was the G200 (8MB) .. continued making it till just into the new millenium. The G250 went by relatively unnoticed. These cards saw some initial success ... but their mindshare with the public was short lived. From then on Matrox's offerings never were able to compete in performance or graphics with the likes of nVidia and ATI. At that point Matrox focused on the industrial / commercial market. The last time I used one was in 2013 where I powered four large 1080p screens for a Power Plant Monitoring system's overhead display. The selection had nothing to do with the card's performance, or visual acuity ... it's just because it offered the ability to connect for screens in 7680 x 120 configuration.
As for buying a card today, for one, your image is dependent on the capabilities of the display. The best screens available today are 165 HZ, 1440p IPS and are running around $750. Unfortunately, the card (1070) needed to drive them in a gaming environment are running over $900 today. At your budget of 150 (150 what ... I'll assume US dollars), you are looking at a GTX 1050 ($150 - $250) depending on model) or AMD equivalent (RX 560) . Either should satisfy for movie viewing and light gaming.
As for not doing adjustments on any new monitor / card ... no, they are not delivered set up perfectly. No two monitors arrive at your door looking the same. That's why you have sites that offer ICC profiles that will get you very close yoo where you need to be for any particular model. There may be multiple profiles for different refresh rates, if you are using MBR techgnology oir even if there's aprefernce for Display Pro, Spyder, X-rite i1 Pro, Lacie or ColorMunki
