I am looking at upgrading an old workstation caliber machine (which is no longer workstation caliber) for the purpose of CAD (Solidworks) design. The end goal is to have the machine run dual monitors, Solidworks (up to 3 files at a time), Email Client, and occasional light web-browsing (no gaming/java/streaming music) without crashing.
The upgrade involves maxing the memory to 4GB from 1GB and swapping to a newer/better video card. I am extremely limited in my video card choices by the fact that the machine has a grand total of 1 PCI Express x16 Slot capable of supplying up to 150 watts. The machine currently has an Nvidia Quadro NVS 285 installed. I should also mention the machine has an Intel Pentium 4 CPU but that is staying, just not enough power in an upgrade to justify it.
Given the limited choices I have and considering the purpose of the machine should I:
A.) Go the route of installing a newer Nvidia QuadroFX Card and pay the high price for the drivers and support?
Such as this Nvidia NVS 420 http://www.newegg.com/Product/Product.aspx...N82E16814133258
B.) Go the route of a gaming card, leave the drivers as is and just go with it?
Such as this Nvidia 8600GT http://www.newegg.com/Product/Product.aspx...N82E16814143112
C.) Go the route of the gaming card and soft-mod the drivers myself.
I am hoping to avoid going the route of "buy new computer."
Lastly I do not have an unbreakable affinity for Nvidia Chipsets or Newegg.com, I just wanted to get some examples quick. Feel free to suggest other retailers and manufacturers.
