FYI: Cyrix 486SLC != 486 - it's more a souped up 386SX; 16 bit data bus, 16 MB max memory, far below scalar.
A real 486 (both DX or SX) has 32 bit busses, larger caches and is nearly scalar. Don't want to spoil the party, but a real 486 is a lot faster.
But: there is a TI486SLC, same design but larger cache (8KB instead of 1 KB) - if you want the fastest, that's the way to go. ;-)
