Hi!
I want to build a pc.i have alraedy r9 290 and o i want a good cpu and mother board
Should i take i5 7500 with asus rog strix b250h gaming i5 8400 with z370 hd3 gigabyte(they say that z370 doesnt suit to i5 8400..)
Or i go to ryzen 5 1600?
Thank u in advice!

I wouldn't say it's totally out of the question. I'm in a thread right now where the OP has a 7500, and wants to upgrade to the 1600. Problem is that's more of side move. It's a bit slower yes, but considering the cost savings it's not a horrible idea either. What I'll say about the 7500 is if the price is cheap enough, it might be worth it. If buying from scratch I'd probably get the 8400 and then the 1600. But if you have anything that can be used by a 7500, 7600, or 7700, those chips are still quite good. And with the holiday sales going on they might still make a lot of sense.

The 8400 is probably the chip to beat. (followed closely by the 8350K.) For a gaming CPU, considering only performance, the 7700, and 8400 are the...

the 7500 is out of the question... lets get that out of the way

the battle is between the i5-8400 and the R5-1600

but overall the 8400 is more of an expensive build at the moment, I would suggest going with the r5-1600 CPU, it will allow you to get readily stabalized (pricewise) parts, you will see by reviews which ones are worth getting. And at the end of the day, they're both around the same performance level in gaming, especially once you would overclock (actually even takes the lead I believe if you get it to a decent OC, make sure to spend a little extra on a good CPU cooler) the R5 CPU - not to mention the threads on the r5-1600 vs the i5-8400

enjoy happy gaming

The 8400 is probably the chip to beat. (followed closely by the 8350K.) For a gaming CPU, considering only performance, the 7700, and 8400 are the best in my eyes. The AMD 1600 and 1600X are right there as well. For a pure gaming rig the 8400 is the performance CPU, with the 1600 pulling up second. But either will serve you well.

Edit: Here is the chart for the 8400.

http://www.tomshardware.com/reviews/intel-coffee-lake-core-i5-8400-cpu,5281-11.html

Basically you want to be in the lower right corner. If you look around the 8400, there are chips to the right of it (more FPS) but they are all OC'ed, and cost more. Even the 8600K and 7700K will give you the same 65-70FPS area, but run $250 and up. You really need to have an OC'ed CPU to cross that 70FPS barrier.

It depends partly on how good your DDR4 memory is too as Ryzen likes fast memory. in general it scales up to about 3200MHz in Dual Channel (i.e. 2x4GB) but I recommend at least 2666MHz.

If you have either LESS than 2666MHz with two sticks in Dual Channel or only a single stick of memory, AND have no immediate plans to upgrade the memory to that level then I'd go with the i5-8400 setup.

*Having said that, I'd probably go with the R5-1600 Ryzen setup if your DDR4 memory is sufficient since the CPU cores are very ROUGHLY comparable but it has:
a) hyperthreading (more total processing power for heavily threaded situations), and
b) the AM4 socket will be around longer, with an upgrade path POSSIBLY later to an 8-core, ZEN2 CPU (which may add 50% or more processing power in th eory for very threaded applications)
 
BTW, I have tried to compare the R5-1600 and i5-8400 but much of the data is contradictory.

I looked at PASSMARK but the single thread values seemed much lower than they should have been based on other benchmarks.

As well, the RELATIVE processing power in AMD Ryzen CPU's should go up in future programs that have been COMPILED with a new compiler optimized to their architecture whereas most programs now are optimized to Intel with less potential to gain.

If you plan to keep the system longer than THREE YEARS I think Ryzen is the best way to go for the gains due to the compiler, the hyperthreading, and the upgradability of the CPU.

Both are very capable CPUs in their budget range. If you can actually get the 8400 cheaper, you go for that, save some money and put it towards a GPU later on.

the 1600 is in my opinion a better rounded CPU, but it is slower than the 8400 out of the box. A moderate overclock would fix that, and it's better on heavy CPU threaded tasks, but that's more of specific scenarios

I echo the sentiment above, gaming wise the i5 8400 is the chip to beat and even an OC 1600 can't quite catch up. Ignore the comments regarding AM4 longevity, get a Z370 and pave a path towards a possible upgrade to an 8600K/8700K somewhere down the road, that'll yield much better performance for years to come.
