There will be a lots of changes in prices and technology by then. My suggestion would be just keep researching web for what is better out there in market at your price range. In this year, Nvidia will be putting out new 800 series graphics card and where as Intel will be launching next gen processor Broadwell too by this year. There will be much prices drop by that time so just keep an eye on things for much improvement.
