You did notice the GTA V results of OC G3258 and OC Athlon x 4 860K with OC R9 290X in
post #273 didn't you?
Yes. The G3258 is going to stutter no matter how well some APU performs in comparison.
As far as I can remember if OC G3258 was paired with R9 290 or R9 290X it was purely for benchmarking or testing purposes.
No, not really. Remember there were a bunch of cheap 290X cards dumped on the market from mining that went into a lot of different machines. Some people who were trying to game on the cheap passed up on locked i5s for cheaper G3258s thinking they could squeeze out more performance from 4.8 GHz overclocks. You know, spare the CPU and spoil the GPU, which is the usual mantra in a lot of places.
Sadly people who would have been better-served by an i3 frequently ignored them. They were terribly overpriced for awhile there, seriously compromising their value vs. locked i5s.
An APU isn't any better in the cases mentioned. Its an illusion to think that something equally as weak is enough to solve all the issues and play on max in a game that got Core i5 and FX8xxx under recommended. The weak APU would stutter just as much.
What you frequently get with the 2m/4t FM2+ chips is just bad framerates overall. Look at the charts cbn posted, for example. Higher minimums than the G3258, but still sub-30 fps anyway. But lets be honest, not many outside of AMD diehards think that a 970 or a 290x/390x goes well with an 860k or 7870k.
