I would switch the GTX650 for an ATI/AMD FirePro V4900, and upgrade to Win 7 or 8 Pro.
It does vary on what you are planning to use SW for... if your going to be making large assemblies I would look at the i7 motherboards boards with at least a Quad core processor. As for Video Card I have seen some performance ratings and the Nvidia Quadro Cards are still outperforming the ATi cards (Sorry Kelvin). The new Quadro K5000 (just bought it in my Laptop) really rocks when using SW generally and does even better with rendering.... but like I said your PC should represent the type of designing you plan to do or what you plan to do in the future.

I usually just buy Dell boxes for all our users and only occasionally do we purchase desktops anymore we mostly stay with laptops, not as easy to upgrade like a Desktop top, but they will usually last a hgih end user of SW at least 3-4 years before and upgrade is needed. Those using AutoCAD get the Lenovo W530's.
thanks guys for answering my question, but one thing...
i have looked up on my current curriculum then saw that we are up to 3D rendering...
i have a question
what I am building will be a home pc/ part time solidwork station/part time play place for my nephews, so, whats the big difference between a gaming graphics card like the one I have mentioned to ATI/AMD FirePro V4900?
how will the rendering speed be affected if I use thoise specifications that i have mentioned?
PV360 rendering is processed by the CPU, so the graphics card will have little to no effect, except when using RealView and manipulating larger models.
You will be fine with what you have. Sure, you would get better performance with an i7 and a Workstation Graphics card, but I run Solidworks on my PC at home just fine with larger assemblies using an i5/ GTX550ti.
guys thank you so much... i will be posting here since there are many people to help here..thanks guys
Windows Home Editions are not supported
+ I would get SSD for OS and software.
