I can't justify spending that much when I can't make it back. I impulsively bought a 290X, when the price was $600, and then watched the price jump $100 over the next few days. I've almost ROI'd that card, but the 7970 would be more of a pain. I already have an XFX 7970, so I kinda wanted to make it symmetrical.
No worries. As you can see from the eBay auction ending at over $500, these cards are heavily in demand. If anyone would like a discount to the going rate on eBay, along with paying in BTC, the offer is here. I'll accept $450 in BTC.
