AMD FX 8320 to Intel i5 6600k upgrade worth the effort?

[dirthurts]

I'm kicking an r9 390 right now (8gb) and I'm considering an upgrade to an i5 for better performance (and mobo, keeping my ddr3 16gb though). I'm clocked at 3.8 ghz now...
My question is, with DX12 rolling in and the AMD processors getting some solid gains from the extra cores, is it worth upgrading to the i5?
How much of a bump and I'm looking at here?
Any thoughts?

Nope not worth it

If you're not going to upgrade your RAM then don't upgrade to a 6600k, DDR3 isn't recommend for Skylake and it's harmful to it.

What kinds of games do you play?

[_I_]

for gaming, yes

nearly twice the core performance, where it counts in gaming

Does not always equate to 2x the performance in games.

The type of games he plays is relevant.

I doubt it. Is there a particular game you're thinking of where the performance is lagging? If there are some single/dbl thread games that require more oomph you can turn or 2 or 4 of the cores and massivey OC the 8320; esp if you have a good cooling solution.

with a gpu thats being held back by the fx cpu, it can

we also need to know what mobo the op has before suggesting to overclock

Sure, it can.

Usually doesn't. Depends on what he's playing.

If he's playing a lot of MMOs, Civ5, Arma III, etc, then you're probably right.

Disinfo.... yeah FX holds back GPUS, dunno, no fps dips here....

It's not wrong to say a FX can hold back some GPUs. They definitely can. How much so, and whether the upgrade is worthwhile, depends on many factors. It's not as cut and dry as _I_ likes to make it seem. If he plays mostly FPS, for example, the upgrade would be mostly worthless, since the 8320 can run pretty much any FPS at 60+ fps.

No doubts, its worth to upgrade. And don't bother about DX12.
First, i5 have exactly the same number of physical cores as FX-8/9xxx.
Second, expectations from DirectX12 most probably overrated.
Third, nobody knows atm, whether DirectX12 will become popular or not. It can lose to Vulkan.

Correction FX have 2 FPUs per core

What do you mean by that? Can you explain your statement more clear? And what is FPU from your point of view?

[_I_]

each fx module has 2 cores sharing l2 cache and a single fpu
fx8-9 have 4 modules
fx6 has 3 of 4 modules enabled
fx4 has 2 of 4 modules enabled

Probably he misused term "FPU" instead of "floating-point capable execution unit". In such case, he is right - FX really has 2 ALUs for floating point operations per core (module). But Core i has 4 such EUs
