Hi, i've been wanting to get a new computer for a while now, and have finally decided to put something togater. Things i have: OS(64 bit Vista)/LCD/Keyboard/mic/speakers Aii so I live in Canada and my price range is around 500, I am willing to pull up to 600 if I need to but really would love to stay near 500. I am not a huge gamer, but I do play games, but not very often. My main use of the computer will be using CAD software’s, such as Autodesk AutoCAD and Micostation. I also do occasional video/image editing. And of course watch movies and stuff. So I found this prebuilt refurb system; Price: $430 (CAD$) Gateway DX4820-05H (Refurbished) Intel Core 2 Quad Q8200 2.33Ghz 6GB DDR2 Memory, 640GB SATA II HDD, ATI Radeon HD 4350 512MB, Super-Multi DVD�R/RW, Card Reader, 7.1CH HD Audio, GigaLAN, IEEE1394, Windows Vista Home Premium 64-bit (Windows 7 Upgradeable) The other option is to build Something my self. I've looked at a Barebone kit and here it is; Price: $600 Barebone kit: http://www.tigerdirect.ca/applications/searchtools/item-details.asp?EdpNo=5633678 Video Card: http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=4111742&sku=E145-9504 Any help is greatly appreciated. I have looked at the Techspot PC guide and wanted some more help. The truth is that i am not sure abt new systems out there and if i need something better to do the tasks i want to do.
