Interesting that most people seem to be going for nvidia gpu's either the 750 or 750ti.
I thought an AMD gpu would provide a better performance / cost ratio. such as the R7 260x which price wise is between the 750 and ti, but performance wise it's closer to the Ti.
Or for a little bit more than the ti you can pick up an R9 270.
The haswell celeron could be a bit of a sleeper hit, it depends if amd sorted out there cores such that 2 amd cores is approximately equal to 1 intel core.
