Whats the difference between a regular XEON x3323 and an HP XEON x3323. I saw an HP XEON x3323 on amazon for $10, and thought that it meant it came from an HP system, till I noticed in the description that it has 16mb of cach. I have an optiplex 755, and saw that you can use a XEON x3323 provided you use a lga771 to lga775 adapter.
