Solidworks 2012 running slow?

We have recently updated our Solidworks to 2012 from 2011 and it is running slow when selecting commands. For example, when in assembly mode selecting 'Mate' can take up to 5 seconds to come on screen.

This is quite frustrating when you're used to it being instant and also getting a few software crashes each day. The autorecover doesn't always work thus resulting in backtracking my work progress.

Can anyone tell me if my PC spec is sufficient enough?

Dell Precision 390:

Intel Core 2 CPU - 6420 @ 2.13GHz

8gb RAM

Nvidia Quadro FX 4600

Windows 7 64 bit.

Kind regards,

Ronnie
