Yea my familys computers are like icefire's setup......
I have the top PC, (see specs in my sig)..
My sister has my old pentium 4 1.7 Ghz with 512 MB SDRAM and Onboard video AND sound,
My smaller sister who has an Athlon 1200mhz and a Geforce 2 MX 400 64 MB,
then my Moms, the Athlon XP 1700+, the crappiest computer of all (suprisingly, even though its the 4th best...)
Then my little sister and little brother have a computer I made for them for christmas, using an Athlon 850mhz, 256 MB SDRAM, and Onboard video and sound... (they're gettin my old sound blaster live installed shortly...)
My dad has a Dell Inspiron Notebook with a Pentium M 1.6 Ghz with 512 MB of RAM, and Intel 915 video, and its pretty quick...
my mom has windows 2000, the rest of the PC's have XP Home or Pro on them.... They're all networked together on Cable internet using a netgear router, and the they are ALL IN ONE ROOM!!!! its always hot where i am...
