Pretty much totally redid the entire price range guide. All ratios are taken from Tom's Hardware benchmarking and NewEgg.com's prices. NewEgg has proven to consumers over the years that it is the pinnacle of computer hardware resellers due to its incredible customer service and return policies, hence me using it over other sites. Tom's Hardware's interactive VGA charts make my life a lot easier with this guide, so I'd like to thank them also.
*EDIT*
I apologize for not updating the guide for so long, but I was quite annoyed at the lack of huge boosts in the videocard industry so I waited before I made a big update. Also, no offense to the above poster, but most of the information and ranking in that list is erroneous and will lead people to buy videocards which are a complete ripoff. Please refer to my guide for the best deals now that it is updated. Thanks!
