I have my AMD 4850e here collecting dust. I used it for a couple of months (I really don't remember, but at most 6 months and overclocked it to 2.8ghz (stock being 2.5ghz) for a month or 2 in that span. It has never been run at over 140F and has generally been well taken care of. It still works, other than that that there is really nothing else I can say. I will complete the transaction through PayPal, so you have their security there, and I live in the US. I'm asking 55 shipped but it's not set in stone. Also, I have 2 never touched AMD heatsinks, the one that came with the 4850e, and the one that came with my 7850 Kuma, if you want either I'll throw them (both) in free of charge but it might increase the shipping price so I'd have to charge the difference. But who wants the crappy stock AMD heatsinks?
