"It's All About the Pentiums" is a song by "Weird Al" Yankovic. It is a parody of "It's All About the Benjamins (Rock Remix)" by Sean "Puff Daddy" Combs and focuses on the narrator's obsession with his computer's hardware.

Yankovic spoke to Sean Combs personally on the phone to make sure that the parody would not emulate the 1996 Coolio incident. Yankovic has admitted to writing the song a few days before the entire album had to be mastered:

"I almost always record the lead vocals first. The only exception that comes to mind is 'It’s All About the Pentiums.' I had pitched Puff Daddy on the parody idea, and by the time I finally got his official approval, we were already in the final studio sessions for 'Running With Scissors'! It was such a last minute addition to the album that I had no choice but to record all the instrument tracks and background vocals first, just to buy me some time to come up with the lyrics. We were mixing the last few songs on the album by the time I finished writing the lyrics to 'Pentiums,' and I wound up recording the lead vocals just a couple days before the album had to be mastered. It’s a good thing I work well under pressure!"
