My best advise to you would be to go to newegg.com or to where you orignally bought the parts. Price it all out and then try and figure a fair depreiciation for the time that you've had it and also figure in any overclocking and extensive benchmarking and the such. This should bring you to a fair market price and if it's too much I'm sure there will be people here who will tell you so. Hope this helps.
