there is a "GTS" version maybe that's what he mean.. 8600 GTS its a very old card to be honest if it isn't working just throw it away.. cause that card at the moment isn't even worth 20 USD brand new.
So my advice is State A price sell it for like for 500 JMD..
Cause if a computer literate person was to make an offer like my self.... I would offer to come get it from you for free
cause the gas im gonna waste to come get that card wouldn't even be worth it.
