XFX 8800GT (2x)

http://media.photobucket.com/image/x...150-272-04.jpg

Those are the two XFX 8800GT that I have (stock versions, but that same cooler is what I am showing you in the picture). Both work perfectly, and have not been registered to XFX (I didn't know I had to when I bought them). Anyways, I was wondering what they would be worth, because I would like to get a GTX 260 216 (I am getting a new monitor soon, so my SLI would be a bottleneck.

How much can I get if I shipped to both CAD and US.

They have all the cables and stuff with them too. Barely overclocked, and I never kept the overclocks for more than a week or so (because they max everything I throw at them at stock, so I don't see a need).

Please let me know how much they would be worth seperate and together, as well as in what currency the appraisal is in.
