It is quite possibly a P-75+. &nbsp;I plan to upgrade to a Cyrix 6x86 P-133+ in the near future but in the meantime I want to install Win95 OSR2 on a new hard drive and run it for a week or so.<br />

 &nbsp; 6x86 is P-75+. &nbsp;The P rating on the 5x86 is P-75. &nbsp;The 5x86 is &nbsp;kind of a souped up 486, the 6x86 tries to be a Pentium. &nbsp;If your budget is tight, then the 6x86 is a fine chip (provided it works), but for performance, I would recomment Pentium, Pentium MMX, or K6... &nbsp;Remember that the cpu speed setting for the P-133 + is not 133, but I believe 110, which is 55x2, so if your board does not have a 55Mhz bus speed setting, you will not be able to run at P-133+, but you will be able to underclock it at the P-120+ speed (100:50x2). &nbsp;Use a good fan, and set your voltages properly.<br />

 &nbsp; Actually, only the 5x86 133Mhz has a P-75 rating. &nbsp;Incidentally, if you do have a 5x86 you will have to upgrade with both a board and chip, and you have to make sure you have enough memory to fill a bank. (Generally, pentium class boards require two matched SIMMS per bank). &nbsp;If you have the 6x86, you only need the chip.<br />
