Yeah, it is a predicament no doubt. Maybe because of the memory frequency - setting up the timings yourself may not be quite as fruitful as a higher clock at default.
PS: 512-bit interface doubles an equal return upon overclock so there is twice the emphasis on memory frequency.

Why not this at $40 less with the same or even slightly better performance than that 290X?

You are better ignoring him like all others, he only creates trouble not solutions.

Why get a GPU with less shaders than 290X? Its $25 less when rebates have been deducted, and you get 10% less shaders

Nice try troll. Everyone here is discussing GPUs while you come with your personal flamebait and really offer trouble.
If you can`t see the irony in that, its time to get a mirror.

Maybe because 290 scale exactly as 2x270X in crossfire configuration? Extra shaders on 290X don't translate into anything.

Uhm. they do, but the shader scaling is not linear. Look at 6950,6970,6950 with 6970 clocks, and 6950 with 6970 clocks and unlocked shaders. The difference is about 3-5% with the extra shaders unlocked.

First counting rebates is often like counting future lottery winnings as income. By the time you get the rebate you often have forgotten about it. Plus rebates mean nothing at the time of purchase unless they are an instant rebate.

While the 290X has more shaders it also has lower performance numbers. So your saying a number on the hardware means more than the real life performance usage? The 390 has as good or better performance, uses less power, generates less heat and costs less out the store? Again why by the 290X?

i dont get their concepts of rebates, its such a round-about way of issuing a discount.

What GCN 1.2 has over GCN 1.0:
Fp16 compute precision support (what Pascal will be adding to Maxwell)

Data parallel instructions, the ability for each SIMD to work on two compute instructions concurrently. Switching between both in a single cycle (known as fine grained preemption).

Improved compute task scheduling (8 ACEs instead of 2).

And yeah, the improved tessellation performance as well.

The Tonga architecture will be far superior to Tahiti under DX12/Vulcan APIs.
