Performance problem on good machine

Hi all,
We're using SolidWorks 2008 with Sp2. Recently we bough workstationmachine from Fujitsu-Siemens (2.6 GHz Xeon CPU, 6 GB ram, FX4600).System should be able to handle over 250 Poligons per second(according to nvidia) but SolidWorks liveview is really slow. Onthe same model on other machine is much quicker with rendering it.I'm using latest nvidia drives, resolution that im workin in is1600x1050 OS is Windows xp 64bit. Is there any commond problem withconfiguration like this ?SolidworksAdministration
