I was recently offered an XPS 8700 with a fried motherboard for cheap.  But I have to travel quite far to get it.  The original owner said he bought it direct from  DELL with the   GPU installed, and I saw that it has heatpipes. (So its not the GT 745, it's something bigger).

Does anyone know what factory GPU options DELL offered for the XPS 8700, that were large enough to have heatpipes?

All the Google searches come up with much smaller cards.
