I notice they always want $160 -- not $150, or $170, but $160 -- as in, they'd like to make a nice even "fifty" on their deal.
I've run into several of these guys -- but they (and their would-be customers) need to learn a few things:
1. The 5830 doesn't make BTC fly out of your orifices. It's just a good video card for mining at the $110 price point.
2. The 5830 is one of the best entry-level mining cards there is -- when purchased for $110 or $120.
3. There are other cards that perform as well -- if not better -- at the $160 price point.
...and...pay attention here, boys...
4. The BTC mining market, while still profitable, is hardly in a "manic growth" phase anymore (or at least it shouldn't be). Newsflash! BTC aren't trading for $30 anymore. Anyone who's bought cards for a quick buck is LATE TO THE PARTY. As in, 3 weeks late. And we've had one Difficulty Reset since those halcyon $30 days as well (with another coming at the end of this week!)
5. The 5830 brings in 0.26 BTC per day (going by 255 MH/s). At the current market price of $11/BTC, that's $2.86 BEFORE YOU SUBTRACT ELECTRICITY and any conversion to USD fees. It will take a long time to earn $120 back, nevermind $160.
