Hi i was wondering im looking to upgrade from a gtx1080 with a ryzen 5 5600x and i found a used RTX3080 FE unit for $500. Anyone think that is a good deal? IM very cautious on buying anything used but he did say he upgraded to a 4090 unit and to ease my mind would take my info and let me take the unit home and put it into my system to verify it works then he said he would take payment via Venmo which i dont have after which is odd to me someone would do that? Almost sounds like a scam but just trying to see if anyone has experienced that before? Thanks!!
