A few weeks back my PC died and a friend sold me his bare bones dimension 2400. I tacked on my old hard drive and an old 1GB ram chip and decent PCI graphics card and its up and running pretty good. However it drags a lot, and I believe this is due to the total lack of cache memory in the 2.4 ghz celeron processor. I've gone through a few threads here and I believe I have found what I need to upgrade my PC quite nicely, but I want to be sure before I give what little money I have in reserve on something that doesnt work.

Option 1 is a little slower, but it seems more legit as well:

Option 2 is faster, and also seems to meet the requirements.

Should I swap out my Celeron for one of these, or only one, or neither? I just want to be at least 80% sure before I go ahead.
