A few questions about gpu's

Hello, I was reading about Directx12 coming out next year, and in the article is stated that dx12 is going to change how many commands the cpu gives the gpu in one cycle, instead of giving one command in a linear continues line, the cpu will give the gpu a complete list of commands instead, wouldn't this effectively remove cpu benchmarks to some extent on a high amount of systems ?

My other question is about graphics cards power supply, The TDP is the maximum power draw of the entire card itself correct, if I am right on this then how do benchmark and review sites post gpu's going way beyond their max power draw

Example: http://www.tomshardware.com/reviews/radeon-r9-290-and-2...
most sites I read state that the r9 290 has a tdp of 275 watts, but most there are drawing 300 and up, how is this possible ?

THANK YOU !

As far as power use testing, that's total system power, not just for the card. The TDP figure is a specification from the manufacturer on just the card.

No single card should need that much (though the super high end $1000 sort of dual-GPU cards might come close) but an SLI/Xfire configuration would.
