No.
HTC made several changes a while back that made even "good" computers, things that could run Doom3, choke and chug. I remember because I was forced to upgrade. I didn't upgrade so I could play AAO better. I could already play that. I didn't upgrade so I could play HL2 better. I could already play that. The game code alone in AH2 changed to the point that my already-adequate system was unable to play the game properly.
There's a point when you have to say "No, no more bogging down my computer, it does everything else fine why are YOU making your program so needy and all-consuming when nobody else requires this power"
By your logic, Windows Vista minimum requirements' bloat are required, expected, and nay NECESSARY to force everybody in the nation to upgrade to a dual-core with 1GB ram just to run the OS by itself, not counting programs on top of that.
So you see, code bloat that forces hardware upgrades is not a good thing. Not when everything else out there runs fine and only this one game slows down. There's a point when you just have to say "no."
So,
"No."
