most of the 980m that I found are brand new, but even those few used one are sold for a very expensive price in mine opinion. Not to mention that i have to buy the heatsink too, which in total are like $1000 upgrade, no way ! I rather build a mini gaming machine for that money... I know about the beast adaptor on mPcie and in fact I think I like more this idea, it's definitely cheaper. but again I don't know after which card I will get zero extra performance due to the limitations of the mPcie x1
