AMD R7 250 integrated

[amdforever]

So I got this computer for around 330- 340 us dollars. It has 8 gigs of ram, AMD APU 7870k overclocked to 4.1ghz stock and 4.5ghz turbo with integrated r7 250 1 gig and assrock fm2a88m-hd+ r2.0. The stock frequency of the gpu is 866mhz but I can overclock it to around 930-940 without any problems(thanks msi afterburner). My question is:
Is it worth it getting a second r7 250 for dual graphics(and if yes which version the ddr3 2 gigs one or the gddr5 1 gig one), or getting a new gpu(for example r9 390x)?

I have low budget and in my country few people actually sell pc parts(I mean like on ebay) so the "how much time and money does it take" factor is also very important.

 

I'm happy with the processor (it rarely goes over 3.8) but the gpu is not satisfying at all. To get 40-50 fps on AC  rouge I had to to lower the resolution to 1024x720p and that's on medium settings. What do you guys think?

A 390x will definatly be bottlenecked by that a10, maby something like a 370 or 380x?

Get a better CPU (i3 or i5, keep CPU if budgeting) and then an R9 380 (or 390, only if getting an i5 to prevent slight bottlenecks).

Get a better CPU (i3 or i5, x4 860k if budgeting) and then an R9 380 or 390.

Umm, the 860k is an a10 7870k without the onboard graphics.

I would recommend something like an i3 or i5 as a cpu upgrade.

Ok let me rephrase my post.

Well my motherboard accepts only fm2+ cpus and I checked and the A10 7870k is the best one so it will be cheaper just to buy a new pc. I don't have that kind of budget. I have a budget of 220 bgn which is around 115 $(for upgrades). The best options I have(the ones I found for now) are 2 gb ddr3 geforce or 2 gigs r7 250 but with the dual graphics that's 3 gb in total.

And I don't have cpu problems, actually the i5-4670k is only slightly better, and in terms of price to performance the a10 is better.
