Here’s a reason not to buy a GPU right now. But the big problem is that the 20nm technology at TSMC and Global Foundries is having trouble. But it makes it pretty clear we are late in the cycle, so if you can wait hang on until next year where you will see 20nm graphics cards and the Intel improvements as well.
Mobile Maxwell in 20nm based on the upcoming Geforce 800 series will also come before the holiday shopping season. As far as we know 20nm GPUs from AMD won’t launch this year, but we could be wrong. It is too early to say for sure.
