Ok, I'm looking to build a custom laptop (or get one built by someone). The one I currently have works fine, but it runs slow at times and occasionally freezes for a few seconds. I can't complain too much about it however, since it was free. Budget is around $800-900 and no more than $1000. I'd like good performance on med-high settings for games such as WoW, Wildstar, etc. I may also do some 3D modeling via Autodesk or Solidworks, so it will need to be able to handle that. Screen size no larger than 17". Country is US and I have most peripherals that I should need.
