In my office I have a few Dell Dimension 4600's running XP Pro 32-bit. We use them to run MS Office and Quickbooks. I currently have a 4600 with a Radeon 9550 AGP graphics card and 2GB RAM that I've used for running Chief Architect X2 with marginal performance. I do my 3D rendering work at home on another computer. I have a Dimension 4700 that I got for free (real estate office shut down and gave it to me). I also stepped up to Chief Architect X3, which I can run on my laptop (Dell Inspiron M5030 w/ Windows 7 64-bit) and my home PC. My thought is to upgrade the 4700 to run Chief Architect X3. Here is what the program needs: PC Minimum* * Windows 7 / Vista / XP * 2.4 GHz processor * 2 GB of Memory * 5 GB of available hard disk space * 256 MB dedicated video card * OpenGL: 2.1 or higher * Internet: High speed for Registration, Video access, and Catalog / Library downloads Here is what is recommended: * Windows 7 64 bit * Multi-Core CPU (e.g., Intel i5, i7) * 6 GB of Memory * 50 GB of available hard disk space * 1 GB high performance video card (e.g., NVIDIA or ATI) The Dimension 4700 as delivered: Mainboard * Chipset type Intel 915G Express * Data bus speed 800.0 MHz Cache Memory * Type L2 cache * Installed Size 1.0 MB * Cache Per Processor 1 MB RAM * Installed Size 512.0 MB / 4.0 GB (max) * Technology DDR2 SDRAM * Memory Speed 400.0 MHz * Memory Specification Compliance PC2-3200 * Form Factor DIMM 240-pin * Features Dual channel memory architecture If I were to up the RAM to 4GB and add a GeForce 9500 GT Video Card (1GB DDR2, PCI Express 2.0), and use it strictly for design work, do you think it would perform well?
