Oh, you bet it can. On my crappy old (1998-1999) 366MHz Laptop, I can get ~25FPS in Quake with UAE's 040 emulation and the P96 driver. Any modern computer will be far better than that.

Try posting an advert on Amibench. Maybe someone who's converted to a tower case is looking to get rid of their original caseworks.
