I have 3 R9 280x cards still back ordered from November.
The cards that are trickling in are only allowing the network to increase incrementally...
Interesting. Here in France you can get any card you want (that are still being manufactured, 7950 are more difficult but still available), and more importantly, at the normal prices, and at reputable shops. For example 240€ for a 280X and 330€ for a R9 290 (these prices includes 20% VAT).
That is quite cheap for Europe, just compare prices with amazon.at. You think you can get any card but that is incorrect. I saw r9 270x cards listed on a local site by many shops. I've contacted more than 5 to find out that they are out of stock..
Mining litecoin is higher, correct, the earnings from mining bitcoin should be higher, but sadly they are not.
