Maybe in the 500-700 USD range, the issue is there are a lot of gaming laptops with much better specs then yours in the 700-900 range and I think many people will spend the extra on that. Also theough int eh fact that you can build a very powerful small desktop for 500 dollars these days I think your best bet would be to try craigslist or facebook market and start at 650 and let a person haggle down to around 550 or 600.
