GRID 2
The final game in our benchmark suite is also our racing entry, Codemasters’ GRID 2. Codemasters continues to set the bar for graphical fidelity in racing games, and with GRID 2 they’ve gone back to racing on the pavement, bringing to life cities and highways alike. Based on their in-house EGO engine, GRID 2 includes a DirectCompute based advanced lighting system in its highest quality settings, which incurs a significant performance penalty but does a good job of emulating more realistic lighting within the game world.
There’s little to say about GRID 2 other than that we continue to get amazing performance out of the game even though it’s still one of the best looking games in our benchmark suite. For what it is worth the 295X2 holds a distinct advantage over the GTX 780 Ti SLI at both resolutions we test – especially at 2160p – but even the relatively slow GTX 780 Ti SLI is delivering better than 120fps at 1440p and better than 60fps at 2160p, so the difference is somewhat academic (ed: 120Hz 4K monitors, anyone?)

Well, not, not exactly. One thing is not being PCI compliant, and that's a thing I can understand. Another thing is going beyond connectors electrical power specifications. If they put 3 connectors I would have not had any problem. But as it is they are forcing components specifications, not simple indications rules on maximum size and power draw.meowmanjack - Tuesday, April 8, 2014 - link
If you look at the datasheet for the power connector (I'm guessing on the part number but the Molex part linked below should at least be similar enough), each pin is rated for 23 A and the housing can support a full load on each pin. Even if only 3 pairs are passing current, the connector can deliver over 800W at 12V.The limiting factor for how much power can be drawn from that connector is going to be the copper width and thickness on the PCB. If AMD designed the board to carry ~20 A (which the presumably have) off each connector it won't cause a problem.

Oops, forgot the datasheethttp://www.molex.com/molex/products/datasheet.jsp?...

Thanks For Link,Finally My Doubts were Resolved.Ian Cutress - Tuesday, April 8, 2014 - link
Most of the power will be coming from the PCIe power connectors, not the lane itself. If you have 5/6/7 in a single system, then yes you might start to see issues without the appropriate motherboard power connectors.dishayu - Tuesday, April 8, 2014 - link
I'm yet to read the review but FIVE HUNDRED WATTS? WOW!Pbryanw - Tuesday, April 8, 2014 - link
I'd be more impressed if it drew 1.21 Jigawatts!! :)krazyfrog - Tuesday, April 8, 2014 - link
On the second last page, the second last chart is of load GPU temperature when it should be load load noise levels.piroroadkill - Tuesday, April 8, 2014 - link
Reasonable load noise and temps, high performance. Nice.You'll want to get the most efficient PSU you can get your mitts on, though.
Also, I would seriously consider a system that is kicking out 600 Watts of heat to be something you wouldn't want in the same room as you. Your AC will work overtime, or you'll be sweating your ass off.
A GPU for Siberia! But then, that's not really a downside as such, just a side effect of having a ridiculous amount of power pushing at the edges of this process node.

"Reasonable noise and temps"? It is shockingly quiet during load for a dual GPU card. And it has incredibly low GPU temps, too.As for heat, not really, only if you have a badly ventilated room in general or live in a warm climate.
