Grayham Posted March 16, 2009 Share Posted March 16, 2009 Hi, After 7 years of faultless service its time to trade my old pc in. I am going to attempt to build my own this time. The PC will be mostly used for 3D AutoCAD and Revit with the possibly of some rendering. I have a budget of around £700. I have listed the possible spec below, but the area that is puzzling me is the processor. As AutoCAD is ram intensive would a faster dual core be better suited than a slower quad core? Any comments or help will be most appreciated.

manhattan Posted March 17, 2009 Share Posted March 17, 2009 id go for a workstation video card if at all possible. I have 2 similar (slightly lower spec) BFG cards running SLi and they really arent much cop at large cad files compared to even a reasonably low end quadro card. Also you may have problems with the Arctic Freezer heatsink & fan with that motherboard. I bought this same fan to go on an asus P5N 32E board & the large copper pipe running around the perimeter of the socket (which asus use on many of their boards now) doesn't leave enough room to fit it. In the end i used the stock fan from the Q6600 processor which for a stock piece of hardware is really not that bad. Sorry but i cant give you definite advice cos im not familiar with this particular board other than that definitely an OS which can utilise more ram, as dum said.

Ritch7 Posted March 17, 2009 Share Posted March 17, 2009 when asked this question the best answer for the basics is to visit autodesks site and see what specs (like RAM etc) they recommend for running of whatever program, in your case 3D and revit and base it from their then customize Quote Link to comment Share on other sites More sharing options...
chicoman Posted March 19, 2009 Share Posted March 19, 2009 Just built a Cad system for Inventor 2009 SP1 the other week for a client and thought I’d share. Inventor uses Direct 3D now so a Quadro is a waste of money atm. If you a can go for 4GB or even 8GB of RAM if you can fit it in the budget as long as you go with a 64bit OS. Also a higher clocked dual core CPU will help a lot more than a 2.4GHz Quad at least for the next while in CAD anyway. So if you can, grab the E8500 or E8600 instead of a Quad. Another big improvement would be a faster drive something like the Western Digital Velociraptor WD3000GLFS 300GB SATA2 10000RPM 5.5MS would make a difference compared to regular 7200RPM drives. I went for the following since my budget was fairly small and meant for very small assembly’s and no rendering : Antec Sonata III Black Mid Tower Quiet Case ASUS P5Q Pro LGA775 P45 Motherboard Intel Core 2 Duo E8400 Processor 3.0GHZ G.SKILL F2-6400CL5D-4GBPQ 4GB 2X2GB DDR2-800 Memory BFG GeForce 9600GT OC 512MB 1.8GHZ Video Card Western Digital SE16 320GB Hard Drive Microsoft Windows Vista Home Premium Edition 32BIT The client called back yesterday to say that he’s VERY pleased how the computer runs. Had somebody else there that also used IV and was also impressed for the price. PS: I’m not sure you can fit that 9800GTX+ in that case though. I’d go for the Antec Three Hundred case or similar that has the drive cages facing the card which will allow you for more space if need it. Also make sure you get a decent PSU. Just because it says it’s 800W doesn’t mean it of good quality. Cheers. Quote Link to comment Share on other sites More sharing options...
