Released February, 2013
  • 600 MHz
  • 1 GB DDR3

The Radeon R9 295X2 is a great GPU, don't get me wrong, but if I had to choose between two faster GPUs than a dual-GPU offering, I would nearly always choose the dual-GPU setup.

There are other games that are more stressful overall, but this is likely the game most stressing of DX11 performance in particular.

In The News From around the web

On the prototype Radeon Pro SSG the M.2 slots are actually able to be seen as drives by the system and OS so it is essentially acting as if there was a PCI-E adapter card in a slot on the motherboard holding those drives but that may not be the case should this product actually hit the market.
Several commentors mentioned using a PCI-E based SSD in a second slot on the motherboard accessed much like GPUs in CrossFire communicate now (DMA over the PCI-E bus) which is an interesting idea that I had not considered.
If it's for both the GPU and display, I would still wait.
If you can wait it out, I would really suggest you do as it's not only going to be great when it comes to new GPUs - but the older video cards should drop in price, too.
My current system is a 2500k and GTX 670, so the upgrade bug is biting hard, but i can also wait, as the Rift and the HTC Vibe wont really be widely available until the Summer.
On the other hand, if you needed to (or anyone else reading this) buy something now, then the price drop on the R9 Nano has been a great thing, and good timing.
That’s simple, with the program running and the realtime graph disabled (it polls NvAPI constantly adding noise to the mass of API calls).
What it contains is a full account of the process of creating an overclocking tool beyond the constraints of common utilities such as MSI Afterburner.
