Hey everyone, Just have a few questions about a new PC build. I need the Computer for basic use and AutoCAD and Inventor 11. I have been looking at the Pentium D processors, and i think im going to get one but not sure which one is best for price and performance. The prices go from $83-99. I looked at the 805 2.66Ghz and the 820 2.8Ghz. What is everyones take on these? Im not sure of the Motherboard yet, but i have been looking at the Asrocks in the $60 range. Any specific model stand out from the rest? I need to know of a good computer case around the $50-60 range. Should i buy a power supply seperate or with the case? Im going to get a HD around the 80-120GB range. Which are the best for the price? I need to know of some graphics cards that are good for CAD. I do not play any games or anything with my computer. Can i just use a 128 Graphics card? Im going to use onboard audio with a motherboard unless it comes without. Im kinda on a lower end budget. Tell me what you think. Thanks in advance for all your help!
