What is this?

[Entity]

I am new with computers, so I will just list all the information I think is needed:

-Desktop computer

-80 GB Ultra DMA Hard Drive

-Intel Pentium 4

-x86 Family 15 Model 2 Stepping 9 GenuineIntel ~2800 MHZ

-Total Physical Memory: 512 MB

-Total Virtual Memory: 2.00 GB

So...like I need to know what this cpu actually is on the pentium site, and also how good is it for gaming. Also, if you can, please compare to this: http://www.futureshop.ca/catalog/pr...id=25315&PCName=laptop_deals&logon=&langid=EN
