Which processor for game developement?

Well that was a very bad choice. APUs are low end, low cost, low POWER processor, mainly for the 'mainstream' of just 'getting to my email, facebook, and youtube" .



Okay the problem here is 1) your clueless about computer (seems obvious by your information your providing) components - which is VERY BAD for a game developer 2) your not properly funding yourself to meet the 'demands' you expect out of the equipment your INVESTING into.

To address #1
I would IMMEDIATELY stop and just buy Idiot's Guide to PCs and read it to understand the components YOU will be programming for, and obviously need to know what they do so you can make a proper 'decision' on what system you need. This would both benefit you professionally, as well as save you money / time down the road for any computers you own (many over your life like cell phones).

STORAGE: HardDrive, USB Thumb Drive, SSD, etc. - ALL Code is stored here long term, like your stomach, to 'use' to do something with the computer.

MEMORY: RAM - This is like your brain when you try to think about things NOW. So budgeting for this computer, or when you looked up those computers, this is the stuff you 'loaded' from your storage, to 'think on', but it isn't ALL the code in storage or ALL the code necessary (every computer in the worlds spec and price range) to do the job, just enough that you can 'think' on it.

CPU: BRAAAAAINNSSSSS!!! - This does the actual processing or thinking of the computer, this is important because you need to think it is like your brain. If your working on the game code can you suddenly spit out the 3rd quote of the fifth chapter for Literary class? NO, because your 'thinking' of the game code, having loaded (from storage to RAM) just what you need to 'think' about the game code, and suddenly can't yank out some abstract other idea right? Same for the computer, it processes the 'one thing' it is working on; so they made Multiple CORES (Dual, Quad, etc.) to provide more 'brains' to think 'with' to speed things up. Again THINKING though, not actually DOING.

GPU/Sound/Wifi/etc.: COMPONENTS - The 'cheap' normal is dumb parts, like your fingers, feet, etc. to DO the actual work that you 'thought' (CPU) should be done. Make a picture on screen, make a sound to the speakers, send the email over the net, etc. These parts rely on the CPU telling them, like when you think 'real hard' on typing, exactly every step with no mistakes at all, so that the CPU and RAM get 'busy' telling the fingers to 'type this sentence' not rely on the fingers to 'sytp ehsi tensteb ce' - LOL . This is what happened with your ASUS, your system was so 'busy' (slow) doing one thing or another it wouldn't 'respond' when you were already ready to do something else. A way to FIX THIS is to buy SEPARATE components (Sound card, GPU Card, etc.) that have dedicated RAM (Cache) and a processor dedicated to JUST that job; GPU does just graphics not sounds, etc.So when the CPU/RAM go to talk to the component, the component 'writes it all down' (RAM CACHE) and then does the job (Processor) on its own without needed to be micromanaged by the CPU.

OKAY all boring man, TLDR! - well you need to because if you don't understand ABOVE you won't get what we / anyone will be saying in response to your question, and WHY it makes it a difference.

to answer 2) given what we said above, your outlining you WANT
A) Portability - laptop : This can DOUBLE the cost as compared to a desktop because you don't wish something that will burn your lap when used, doesn't weigh 9-12lbs to carry around (not exaggerating) all fits into ONE CASE not seperate screen case etc. - all this COSTS money to manufacture.
B) GAMING - THIS WILL with A DOUBLE the cost or MORE of your system, because to game (see above) you needed DEDICATED GPU - NOT sharing like your ASUS the video 'creating' , Integrated/ONBOARD video shares the CPU/RAM as I noted above.

All systems you provided were CHEAPO LOW END for the masses computers, you need to SERIOUS increase your funds, you WILL NOT get a $300 system to be able to do ANYTHING better than the ASUS, period. You need to be thinking MINIMUM $700 for a Moderate Gaming Desktop (your citing games that are beginning 2013 titles that need at least a i5 Core, 8GB RAM, GTX 680 to play 'like on Youtube' - http://www.systemrequirementslab.com/cyri?gameName=Crysis-3&itemId=11526&p=r) which is about $1000-1200 Laptop to do the SAME THING. Again this is for OLD titles, these sorts of specs are "LOWEST PLAYABLE" end for current titles (Assassins Creed Unity, COD: AW , BF4, etc.) .

So in summary, you need to DRASTICALLY increase your funds over what your paying for these low end PoS your citing, you need to make sure it has a dedicated graphics card if your going to game. It is PAY to PLAY on PCs, the more you pay the better you play.
