A few weeks ago, I ordered a used 290 from a user her on HF. When it arrived, it would work (sort of), but once you started using the 3d part, it would make a high pitched whine. Then it started artifacting and going to a black screen after a little use. I contacted the seller and he asked me to work with him so he could arrange for an RMA to the manufacturer and refund my money. I went ahead and purchased a replacement card, and gave him the info he needed. Since then, he has not contacted me (been about 2 weeks with no response), and I'm stuck out almost $300. I have sent him several IM's on HF and a couple of emails to his Paypal address, and gotten no response.
