I've decided to build a new computer for myself and have put together a list of parts. This seems like a great place to get advice about this sort of thing, so any suggestions for improvement within a reasonable margin would be awesome. Thanks in advance. Also, I do not plan on using the crossfire feature in the motherboard right away.
