Its actually pretty good if you only paid 100 for the computer and it has this thing in it. =] Just optimize you RAM and its just as fast as anything else...(maybe) haha

Great Processor

I've got one of these in my Gateway GP6-400, this processor the 550 Mhz, is inside a shroud I guess for cooling purposes, (pretty wild looking), I have 160 MB PC100 SDRAM but will upgrade to 384 Mb (can't wait). I have Windows 2000 SP4, with all the updates. Handles all processes with ease, especially the internet. Just need to install a bigger HD. Overall I'm happy with this system. Definitely holds her own, even compared to today's processors.
