One of these days when GPU prices get back to Earth and I'm done with my PS3 backlog I'm going to upgrade my GPU but I don't know what to do with my old hardware. Right now I have 2 x Galaxy GTX670 4GB cards with Kraken G10's and Corsair H55's. My next GPU will probably be something with a factory 'hydro' kit or I'm going big with waterblock and custom loop. Is there much of a market for some old ass GTX 670's that don't have their stock coolers? Is there much point in trying to sell those Kraken G10''s? For the Corsair H55's one of them looks like it got a tiny leak and grew a gross little wart of something so that will be trashed while the other looks fine. If I want to toss can I just E-Waste it at Best Buy?
