Ok, here's the deal. I have a Radeon 9100 that I bought for $72. The fan made a loud buzzing noise & vibrated a lot, so I RMA'd it & got a replacement. Now the one I have now is making a similar buzzing noise and I have a GF3 ti200 coming shortly as part of a trade. If I RMA this one will my credit card be credited or will I get store credit? And again, what do I have to do to let them know what I'd like to do?
