I've upgraded to a 670, and have no use for this GPU anymore. It's been owned and operated by an adult in a smoke-free household. It's always been kept cool and never overclocked beyond the factory settings.
These sticks include the heat spreaders, which give them additional height, so they shouldn't be used in PCs where massive CPU coolers are also used. They were given to me as a gift, and used only briefly until the socket 1366 motherboard I'm used decided it was only going to use three sticks at a time, so I upgraded. These are being sold altogether.
These prices include shipping, and I'm shipping only to the US. Payments accepted through Paypal only. PM if you're interested.
