by Jarred-Walton (May, 2012)The A8-4500M takes a pretty major chunk out of the GPU (one third of the GPU cores are gone along with a slight drop in maximum clock speed) while maintaining roughly 80% of the CPU performance, so it can fit into slightly cheaper laptops but will likely drop gaming performance from “moderate” to “light.
by Anand-Lal-Shimpi (Sep, 2012)There are other games that are more stressful overall, but this is likely the game most stressing of DX11 performance in particular.

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.

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.

AMD is using liquid cooling for the processor and graphics with the tubing running up the center column joining the two pieces together to a radiator or radiators.
From the other announcements around Fiji today, particularly the R9 Nano and R9 Fury X, this little machine is going to be a powerhouse with impressive power efficiency and performance per watt – especially for its size!

Now that our review sample arrived this week, I've spent the past few days hitting the TITAN X hard under Linux with various OpenGL and OpenCL workloads compared to other NVIDIA and AMD hardware on the binary Linux drivers.
The TITAN did not win any awards for power efficiency but for OpenCL tests, synthetic OpenGL benchmarks and Unigine on Linux it walked away a clear winner.
