Intel i486 DX2/50
The same as the 80486SX2/50 but with floating point unit (FPU) on-board. The FPU is used for floating point calculations and comes in to play with CAD and Excel. Back then games didn't really use it yet so Doom will run pretty much the same on a SX2. Quake does require a FPU but 486's are practically too slow to run Quake at a decent frame rate.
