Title: Buying Used 5850
Post by: bleedkira on June 07, 2011, 09:56:04 AM
Alright, so I was gonna buy a 5830 from NewEgg to replace my 3850 and start mining, but that opportunity is out the door. I have found someone selling a used sapphire 5850 xtreme on CL and he seems like a nice enough guy, but of course I'm wary. After asking if I could see it in action before buying, he has offered to video it running in his case with a fairly intense 3D game on the monitor, and show that to me when I come to pick it up. I realize this is a pretty big risk, but the price is right. Plus, I have no problem banging the shit out of his door if it's defective until we meet an agreement. Any advice?

$130 -- He also noted he was a gamer and upgraded to a 6xxx series card.

Don't bring money, check it out and offer to meet in a public place (not a parking lot), ask if it's ok to write down his name and address as it appears in his drivers license (if he hesitates, offer yours in return).

Recently a man was robbed at gunpoint when he met a CL phone seller at a fast food restaurant.

I've done CL transactions before, I'm not worried about getting robbed. I'm more worried that he may have OC'd the GPU and damaged it or something like that, and was wondering if the video seemed like good enough proof to you guys.

I Just bought a used 5850 off craigslist

It went well, seller was just a young kid

Paid $170 though, oh well

Had it in my rig getting 300Mhash within the hour

Can't overclock it above 775 mhz though, need to flash the bios I think

Still, overall, happy with the deal

The Sapphire 5850 Extreme just came out 2 months ago (for $150 MSRP), it should have a solid warranty.

He's probably just an average gamer, I'd ask him to run a stress test for a few mins.

Edit: maybe a video which shows the serial, and some stress tests would be great.

I bought all of my cards used on ebay and locally. So far the worst that happened is a fan died and I had to buy an aftermarket cooler.

Recently bought a used hard disk on ebay, a Samsung F3 750 (since they are out of stock and needed for my raid). Checked the uptime on it, it was run for only 124 hours and benched better than existing HD's. Was a bit apprehensive, but in the end it turned out great!  ;D
