- Thats why you save your money and buy an overdrive chip instead of the
- 487sx. Should plug into the same socket on most so you not only get the full
- 486DX, you get it at double the speed.

- This is also what I have heard. I have only a 386-40, but PC World
- had a big comparison of different 486sx systems and found the 486sx 20/25s
- with the overdrive chip to be a better value than a 485/50 system.
