Is in that a bearing i can interconnect 3 computers together?

for example if i have 3 computers with this spec;

2Ghz CPU

2GB Ram

250GB HDD

GeForce 6600

could i produce the computers work together joined on one blind and then engender the specs

6Ghz Cpu

3x Geforce 6600

etc.

yes
I suppose if you used linux you could cluster but you'd be wasting a lot of power.
Yes. Use a triangle nouns. Although the connection you want is outdated and has profusely of security issues. For example, you've syncrhonized 3 computers using the nouns specified and one of them doesn't turn on which means that the others won't operate properly. If you connect 3 computers together adjectives of them have to be within good condition and if one is defect the other two won't function the way you expect it to.
