Most NICs and 10/100 or faster ports made in the last year or few will do auto sensing and there will be no need for a cross over.

Can you give me a picture with the cable inversion necesary for connecting 2 computers on UTP directly by cable?

Swap the green and orange pairs. Thats all there is to it.
Most stores that sell computers now-a-days do carry cross-over cables.
Search for EIA/TIA 568A and 568B. Make up a cable with A on one end and B on the other. You will then have a crossover.
Or was it B on one end and A on the other? ;-)
Is there a GBE crossover cable?
Not necessarily. Nowadays many if not all the newer PCs are coming with a 10/100/1000 NIC, and the crossover cable with just the green and orange swapped will not be able to go above 100MB. If both of your PCs are 10/100/1000 and have auto detection to test the cable, they might work okay with a straight thru cable. Remember that 1000 requires both sending and receiving on each pair.
If you use a 'crossover cable' make sure you label it conspicuously on both ends or make it a very bright and unique color, so that you _will_NOT_ try to use it for a straight thru cable, and end up wasting an hour troubleshooting a problem that's caused by the cable.
AFAIK No. GBE always have MDI/MDI-X that detects pair wiring and adjusts accordingly.

Unless you have a Cisco GBIC WS-G5483 which is the one Gigabit device that I've run across that breaks the spec, and doesn't have the auto MDI/MDI-X detecting if its a crossover or not.
There you have to do all 4 pairs crossed. But its pretty specialized, most likely anybody asking for a crossover is asking for a 100 Mbps one.
Isn't that par for the course for Cisco? It's out of the norm for them if it does meet the standards.
