It all depends on what applications you use I guess.
For GCN/Wii emulation, Intel will win because Dolphin can only use 2 cores, and AMD single core performance is (Famously) not great. I do a lot of game developing, so my AMD helps with multi-tasking and compiling, and also lets me use the PC as 2 workstations without a performance hit in applications that can only use half the CPU anyway.
But the OP is using an R7, so games (Not Dolphin) will be bottle-necked by his GPU before they come close to his CPU's potential. Certainly the Pentium G3258 is excellent for dual core applications given its price. I've even seen it score well on BF4 benchmarks. If I was to build a secondary PC I would go for a Pentium G over the AMD A-series.
