Hi guys,

I was planning to build a gaming PC in time for the release of Dragon Age: Inquisition and also to eventually play Witcher 3 too. Being a student studying Biotechnology, I really dont have much knowledge on Computer hardware and components. So I got a friend of mine who's a Computer Engineer to help me out.

So we were discussing my options at a budget and we are at a stalemate and I was hoping you guys could tell me if his rationale is correct.

He suggests I get an AMD A-10 7850K, and get a R7 series gpu.. I was reading reviews of the processor and everywhere they say the CPU power of the APU is underwhelming and has just 4 usuable cores. I was looking at buying an i5/fx series processor and a cheap GPU instead.

My friend says that for gaming the A10 is more than sufficient and buying a more powerful processor is pointless as no game can possibly use more than 4 cores at once and unless one is looking to multitask while gaming, there's no point in investing in a more powerful CPU with more than 4 cores.

Also he says (he's not a 100% sure on this) getting an R7 series GPU to boot with the A-10 shouldn't dilute its performance and they should technically work together using crossfire as the iGP on the A-10 is also of the R7 series.. Lot of reviews I read say that pairing a GPU with A-10 is not going to help much as the APU is not that powerful as a processor and that's better off to run it without a GPU as it strength lies in the much iGP than the CPU.

That's a long post but I hope what I'm saying makes sense.. My main worry is that will game released says 6 -12 mo ths from now work well with the A-10 APU, and if i was looking to improve performance, would adding a new GPU be good enough or would I need to buy a new CPU as well?

The Intel cpu's offer superior IPC(instructions per clock). The 2 cores in that i3 can keep up with the 4 cores of the 7850 and when hyper-threading is used the the i3 will surpass the 7850k. Also a single 270 is faster than a 250x and 7850k running in dual graphics. The 7850k can't be used in dual graphics or crossfire with a 260x. The 7850k only supports dual graphics mode with the 240 and 250.

if your set on getting the a10 7850k get the r7 250x. you can crossfire the APU+gpu, the 250x provides that best crossfire for that apu. you could get an i3 + a r9 270 for that same price as the apu+r7 combo and it will perform better. or instead of the i3 the fx 6300

I would go with the i3 and 270, gives you a much better upgrade path along with better performance. Something like the i3 4150 with a decent h97 motherboard will cost about the same as a 7850k and a decent a55 or a88 board. The H97 motherboard will allow you to upgrade to an i5 or i7 later on.

Is there a reason the R7 250x is a better crossfire pick than the 260x?

Would be grateful if someone could explain why even an i3 +gpu would offer better performance atm than the 7850k? Just curious about the difference..

the passmark of the a10 7850 is 5682 and for the i3 its 5048. considering the price of the i3 is $40 less it easily makes up for the difference in performance. since its a budget build we're speaking of price/performance with whatever you could reach a satisfactory level of gaming. if your curious the fx 6300's score is 6362 but offers no upgrade path.
