Unlike our canned Metro: Last Light benchmark, F1 2012 and Tomb Raider don’t generate their own frame rate-over-time charts. With fewer images on a page, I bundled both tests together.

High Quality isn’t an adequate preset for gauging high-end graphics performance in F1 2012, since the game is either CPU- or RAM-limited all the way through 5760x1080. That's surprising given our 4.5 GHz CPU and DDR3-2133 CAS 9 memory. But it goes to show how fast these graphics cards are.

Given the tight bottlenecks at other settings, I find F1 2012’s results at 5760x1080 using the Ultra preset incredible. I simply can’t believe that air-cooled card is being pushed hard enough to throttle back at this setting.

Tomb Raider’s overall performance reflects some of the differences we'd expect to see between air- and liquid-cooled cards at low ambient temperatures, though a broader spread at lower resolutions doesn't make as much sense.

The good news in that Tomb Raider is smooth on a single Radeon R9 290X all the way through 5760x1080. My test notes show that minimum performance doesn't drop below 34 FPS on any of the tested configurations.

It has a $150 cooler (including the back plate, etc).
Of course Asus has a special cooler too. But Asus had the opportunity to drop its price, and the 290x has indeed dropped by $50 to $100 in the past two weeks. Supply is catching up with demand.
Unfortunately for PowerColor, its LCS 290X has been out-of-stock for more than two weeks. So they get stuck with prices that are at least two weeks old, at least until someone gets new inventory and lowers their price.
Sucks to be them, they should have restocked their sellers more quickly

Did you happen to notice any variability under load for your core speed while overclocked on the LCS card?
I have a Sapphire Tri-X OC R9 290X that is rock solid at its stock 1040MHz, but that starts bouncing the core clock all around when any core overclocking is applied.
With my quiet fan curve, load temps top out around 85°C; well below AMD's specified throttle point of 95°C.
If your liquid cooled cards are solid at 1200MHz, I am curious if Power Tune starts to throttle in a less severe way after going above 70- or 80°C.
Odd, this happens with a +50% power limit and tested with the Metro Last Light benchmark
Thanks for confirming that your test card was not throttling; back to troubleshooting my setup!

Good point; I will have to retest with a cooler fan curve.
Not sure if this will be the issue though as even a 20MHz bump to the core, and +50% power limit added to this, causes throttling with under 85°C temps.
Thanks for the thoughts!

The card will throttle at the specified level of power consumption and/or temperature. The point at which they throttle is configurable-- If you have the card set to target 80°C or 75°C then it will throttle to maintain that temp as much as possible, while keeping in mind the power limits you've set in Powertune.
That's easy to figure out for just the cards (Graphics performance gained / graphics price increased) For the system, there is System Performance Gained / System Price Increased.
making this chart more complicated on this occasion is that the LC card needs a liquid cooler, which increases the system price by $180. So the system price structure compares [LC card + cooling system + baseline system] to [air-cooled card + baseline system].
I'm sitting here looking at a pile of flow plates for my own EK WBs, so I'm wondering which one the manufacturer decided to go with.
