Intel 486 DX2 66?

For many players of video games during the early and mid 1990's, towards the end of the MS-DOS gaming era, the 80486DX2-66 is a popular processor. Often coupled with 8 MB or 16 MB of RAM and a VESA Local Bus video card, the CPU was quite capable of playing nearly every title available for several years, making it a "sweet spot" in CPU performance and longetivity. Towards the end of its lifespan, with the introduction of 3D graphics, the DX2-66 started to fall behind because of its scalar nature and limited floating point performance. The popular first person shooter Quake spelled the end of the 486's gaming reign because the game heavily used floating point calculations, and was optimized for the significantly faster pipelined floating point unit within Pentium. Performance on even the fastest 486s (133 MHz +) was quite poor.
