mohit9206: i don't see having multiple choices from sub 100$ up to ~200$ as a problem.The lower in the price you get, on a budget system, the more a 10$ difference is accounted for. On a 2000$ computer budget, a 50$ additional may only sound marginal, but for someone with a 300-600$ budget, 10 or 20$ on each components might make a difference. More options is never bad, and AMD does not have to work very hard on the "rebadged" models to offer it to market, thus it is worth it for everybody. I also find it funny how 600$+ 290 cards were still selling out, how 280x @ 400$ is still sold out everywhere .. It is frustrating for someone who is on the market to purchase a GPU while the prices are boosted, i've been 3 times in this situation ( personal and 2 family computers build ) since last october, when it is solely for gaming use ( VS mining users ) . Very hard to decide on a 380$ 280x when your brother just paid 310$ for his 2 months before, but as some have pointed out,supply and demand. If "idiots" would've refrained from purchasing 290 and 280 @ ridiculous prices on newegg, the prices would've eventually come down faster.On another note : DON = could you please explain the problem you ecountered using Mantle API for testing ??
