I recently purchased a new system ands have been working on a model with 50 parts. The model consists of simple boxes of various sizes in a square configuration, nothing complicated. I am working in an i7 870 @ 2.93ghz, GTX 460 video card, st31000528as HD, 12gbddr3 ram running win7 64bit.
Rod,
Sorry to say but your GeForce isn't doing you any good and possibly even hurting you with it running. See here: https://forum.solidworks.com/thread/30654
Charles comment on why you don't want a gaming card is right on
