In 20 years we can do it at home (Score 1)

First, ASCI White specs: Name: ASCI White Built by: IBM over a period of 5 years for the Department of Energy

Price: for $110 million. Power: 1,000 times more powerful than IBM's Deep Blue; capable of roughly 12.3 trillion calculations per second

CPU: Made of off-the shelf IBM Power3 processors (well, 8,192 of them altogether)

RAM: 16 terabytes Disk space: 160 terabytes Power requirements: 3 megawatts of electricity (would light up 3,000 homes)

Now let's say 1 Power3 = 1 domestic processor of today... By Moore's law, in 18 months our computational power will double, so:

2^x = 8192
x = 13
13 * 18 months = 19,5 years

conclusion: video games will be very cool in 20 years
