I just ordered my new GTX 670 so I am selling an EVGA GTX 570. The card is in great condition and is only five months old. Product details are in the link.
It retails for $270-300 and I'll either sell it or take a trade.
I am also selling an MSI GT683R from 2011. The laptop is one year one month old and in great condition. The only thing I have done to it is add a few stickers to the lid. It runs very smoothly and has never been dropped or had a serious bang. All product details are in the link.
