HardOCP writes Fermi is somewhat to blame for the demise of BFG Tech:
BFG’s problems were largely graphics card related, but not related to GTX200. Sales and profit margins on that card were quite good actually. The biggest problem was GTX400 (Fermi) allocation. And the only reason they continued to sell power supplies after they got out of the graphics card business was because there were power supplies to sell. But they couldn’t sell them as quickly as they had been used to because once Best Buy caught wind of BFG not being able to supply graphics cards, they dropped selling their power supply product line as well.
