We are often asked what is the best computer for LD Assistant 08 or AutoCAD 2008.
I have found it easier than ever to build your own computer. Sometime back we started building computers using the BAREBONES Shuttle. Below you can find all the components to put together a GREAT computer. We buy our components from NEWEGG.COM. and have found that they give good service and provide products and components as stated.

Design & Drafting makes no guarantees but we have had huge success with NEWEGG.COM and Shuttle computers.

Video Cards

Understand video cards and how they can make you experince with LD Assistant or AutoCAD© better.
With LD Assistant or AutoCAD© you can leverage the capabilities of NVIDIA® Quadro® professional-class GPUs to incorporate high-quality 3D models into your work flow. Easily boost your performance with Quadro professional graphics solutions and create and interact with more accurate product designs without sacrificing visual quality. 

NVIDIA is taking aim at 3-D CAD users looking for a performance boost.
The Quadro FX 3700 comes stocked with 112 parallel processors, 512 Mbyte of onboard graphics memory and a 256-bit memory interface. The benefits of this high-tech hardware mix are higher throughput for interactive visualization while also boosting the graphics board’s ability to handle the large-size models and complex shaders that are so closely associated with today’s CAD.

ATI and Nvidia are back with brand new families of professional graphics cards.
Back in April Nvidia introduced its eighth generation (G80) graphics architecture with the unveiling of the Quadro FX 4600 and FX 5600. These ultra-high end cards heralded the arrival of the industry’s first unified graphics architecture, which uses general purpose processing units which are dynamically allocated to geometry or shader tasks as required.

If you can put the components together you will save a lot of money.
Be sure to read the product reviews by people who have purchased before making a decision.
