What will happen if Vista Ultimate is installed in low requirement computer?

What will happen if we are installing Windows Vista Ultimate in low performance computer.

The low performance computer as i type is meant that the computer is only can meet the requirement for Windows Vista Home Basic.(Home Basic do not have Aero and 3D Flip navigation).

If i am installing Ultimate version, will this disable COMPLELETELY Aero and Flip 3D or the features as i mentioned above is still present in the computer and need a heavy work load to display the Aerdo and 3D Flip?

Yes, the aero and flip 3d features will be disabled. Also in 512mb of ram vista ultimate will run even slower than snail just because in ultimate version there are many more features that need memory. So it will be damn slow. Probably, if vista setup checks for adequate system requirements, it will not even install.

it probably wont run
Those features such as AERO and FLIP will not work, the system will run those heavy duty features based on your system performance scoring which Vista calculates during and after install. If your system doesnt meet the required score then it automatically disables those features.
May work, may work VVAARRYY SLOWWW, may not work at ALL, you do know ultamate waaay more cool stuff apart from just aero and 3D flip right?
