1998 I got PC with 1024x768. Early on I for a long time played demo discs. It's hard to say what I played on max resolution and what just 800x600 to run better, but those demos included Dark Forces II and Delta force.
Some of later games that likely were among first on my various computers include Star Wars: Episode I Racer, XIII, Prey and Mafia 1.
I didn't get over 1280x1024 until couple years ago, having latest PC on 1920x1080 TV, though I'm mostly using it at 1600x900. My first games on this were Dead Space 2, Flatout: Ultimate Carnage and Batman: Arkham Asylum.
Dead Space 2 was perhaps the biggest "HD experience" for me, for better and worse. It did feel kind of like bad CGI in modern movies compared to Jurassic Park or Terminator 2.
In general I've never been really impressed by graphics, it's always been more about how eye-pleasing style and colors are. So I was more impressed by something like XIII or when I only some years back played Okami on PS2.
