Changing The Processor Driver

Hey all..
i was wondering..: in the device manager under processors i have "proseccor" installed,and this is a driver provided by microsoft and is a "Standard processor types" driver.
Now , a driver for intel pentium III exists in the XP drivers, Should i install it ????????

another thing...according to sisoft sandra:

"The IOQD (Host Bus In-Order Queue Depth) is set too low, most likely 1, i.e. no queue. This indicates the depth of the host bus pipelining; thus 1 indicates that no pipelining is to be done on the bus. This reduces the performance of the host bus which is crucial to performance. P6 (Pentium Pro, II, III, Celeron) has an IOQD depth of 8."

How can i fix that ?........

Thanks for your Help..!! <img src="confused.gif" border="0">
