I'd like to have advice on this custom build:

[bartNL]

I'm working on putting together a new gaming rig, but I can certainly use some advice on this.
The current setup as I have it now is as follows:

€189/$225 i5-4590 (4x 3.3GHz, 3.7Ghz boost)
€183/$218 Sapphire Dual-X R9 280 Boost
€73/$87 2*4GB G.Skill @1600Mhz CL7-8-8-24
€126/$150 24" Samsung TN screen, 2ms lag
€30/$36 MS-N630 BAS 630W PSU
€51/$61 1TB Seagate ST1000DM003 (9.5ms, r/w:210/156, 64MB)
€40/$48 ASUS H81M-A Mobo
€0 Crucial M500 240GB, I already got this device.
€0 Custom case, I'm modding an old one.
Total: €692/$823
With regards to prices, I live in the Netherlands, Europe.

I'm not sure about the mobo, i've got too little knowledge of it to really know what's important when one chooses such a part.
I was thinking about the current mobo because of it's low price.
Is it unwise to invest such a small budget in a mobo, or will this one just suffice my needs?
I'm not really familiar with chipsets and the like. The possibility of overclocking and some cool features would be nice, but not really necessary in this case I think.

My biggest doubts are the gpu and the cpu. I was planning on buying an FX-8350, but from what I hear, it's an overkill in areas where you don't really need it, and it lags behind on the areas which are important to gaming.
Hence I went searching for an intel counterpart, which brought me the i5-4590 and the i3-4460.
I'm doubting between those two, the i3 scores a bit better on single-core performance, while the i5 scores moderately better on multi-core performance.

Since I'll use my system primarily for gaming, single- and dual-core performance are a lot more important than overall or multi-core performance.
The chosen intel's score a lot better on this area in comparison with the FX-8350.
I'd like to hear the opinion of you guys on this.

GPU: The Dual-X R9 280 seems to have a good price/quality ratio, but maybe some of you can think of a better alternative.
NB: I don't have a strong preference regarding nVidia or AMD. 😉

I'm also doubting about the PSU(yes,I actually doubt about everything..), maybe it's a bit cheap-ass and quality to match..

It's quite a story, but I hope it's clear to you what I'm planning to do and trying to achieve.
I like to be well informed before I buy anything, since you can spend your hard-earned money only once.
Any help, suggestions, ore remarks are welcome, if i'm thinking completely wrong somewhere, please correct me!
Sorry for my english, it's not my native language.. 🙁
Cheers!

Don't get a low quality psu. Try to get a 80+ bronze psu such as the Seasonic 620. Cheaping out on psu can have catastrofic consequences. i5s perform better than fx in gaming but tend to cost more money. If you only play games that require 1-2 cores, you could get the pentium g3258, it's faster than any i3 and beats most i5 on sinbgle core usage. It can also be overclocked as hell. I would recommend either the pentium or a cheap i5, like the 4440. r9 280 is king in its price point.

I'd rather go for a h97 Mobo as long as you don't plan to overclock the CPU.
The AMD CPUs are good cheap alternatives for multithreaded applications, but not so good in single thread, so overall you will benefit a lot more from an i5 4590 from intel for everyday applications and gaming.

I was already doubting, so this was the confirmation on the PSU I needed, i'll take a better one for sure.
But I think i'll stick with my cpu, as it has just a tiny bit less single-core performance, but is hugely better in most other aspects.
Maybe i'll pick a cheaper i5 indeed. Thanks for the help!

It may have not as many features as the averag tech-savvy may wish, but an H97 mobo starts at €72/$68 in my country.
Since I won't be overclocking anything I don't need support for that, and it's lack of IntelRapidStorage and SmartResponse doesn't really matter to me. The number of sata and usb ports suffice for my needs. So apart from that, is there anything that would make an H97 mobo preferable over a H81 one? Thanks for your response

I think your h81m should be fine for your build.

Okay, thanks!
