I have a question and I'm sure this is asked all the time but I'm getting a hand-me down dell optiplex that I wanted to network to my amd k6 III machine...The thing is this dell is a pentium II 266mhz machine and I wanted to know if I could swap in a pentium II 450mhz or maybe a celeron 450mhz or higher without having to change out everything else (mainly the motherboard)...I don't want to get into a lot of expese since it will be strictly a internet machine...probably more for just tinkering around than anything else but I noticed that pII cpus aren't to badly priced with the p3 out p4 being out. But I do understand that the 440LX chipset may be holding me back...And from looking on dells site they say nothing to the effect that their flash bios update will support more processors but it may but they don't say that explicitly...I included the specs from their site...I'm not really familiar with the intel stuff as much as amd but since I got this system at a good price I might as well do something with it. That's assuming that I don't need a motherboard swap...I'd appreciate any insights as to my options are if there are any related to cpu here...

actual specs below this particular unit is a 266mhz

I can't be sure but I don't think the LX chipset can be taken fast enough(ie no 100FSB), you may be able to stick in a faster celery....

I have PII 300 and recently upgraded from 64mb of RAM to 256, and the performance increase is very noticeable. since RAm is so cheap, if you have 32 or 64 meg of RAM this is probably the cheapest, easiest (just stick 'em in the MB and go), and most effective upgrade path. Especially if the machine is mostly used for internet browsing and common office apps, more CPU power won't be as much help as more memory. Assuming you have 64 or 32 mb right now.

I agree that in your case, more RAM would be most helpful. Plus, when you buy a new PC you can add the RAM you bought to it.
