i got 4 years of experience in computer hardware & building.
first of all, a gaming computer relies more on more gpu power over cpu power.
second of all, nobody will notice a difference between a AMD cpu over a intel cpu doing light tasks. the only way you will notice a difference is if you didn't install the cpu right or you're using both cpu's to 100% usage , which most people don't even do.
third of all, a power supply is what gives power to the whole computer. having a cheap power supply with inferior capacitors means you will increase the risks of having things you don't want to happen to your computer happen. for example : crash, explode, set on fire, take some parts down.
fourth thing, more ram will not give any real life performance. you gain 1-2% more fps by jumping from 4gb to 8gb and while gaming a person will hit usually up to 6gb of ram in use.
i would continue going on, but i'm bored.
Yay finally a counter argument.
The CPU is like the human brain, it processes instructions that are stored in the RAM and executes them. If it cannot process the instructions fast/well enough, hardware like the video card will be waiting for instructions on what to do next. The difference between AMD and Intel is noticeable even if you are not tech savy by running simple benchmarks. The AMD cpu pipeline is crap compared to the Intel one, so a 3ghz Intel cpu will be faster than a 3ghz AMD cpu. Simply because each clock cycle Intel will get a lot more work done compared to AMD. When you factor in things like AVX2 and other extensions, efficient multithreading and context switching you will notice large differences. Here is a read about CPU pipeling:
http://www.geek.com/chips/what-is-a-processors-pipeline-561598/About GPU power vs CPU power, yes graphics are important and I would drop 200-300$ on a video card no doubt. But if it came down to a $100 processor and 200-300$ video card, or $200-300 processor and $100 video card. I would cheap out on the video card. Video card are powerful enough now at $100 to run most games on Ultra.
About the PSU. I have went through 2 motherboards that fried (cheap ones), a video card, and cpu but never a powersupply. Even the crappiest $20 power-supply has not failed me (no capacitator problems). Im not saying to get a $20 PSU infact my PSU ATM is ~$110, but if your on a budget a basic PSU for around 30-50$ will work great. Your not overclocking so you don't need 650W+. Again overclocking may be a different story, and if your messing around with voltages a crappy PSU could fry your hardware or fry itself. But to really mess with voltages you need some tools and knowledge (not just bios changes).
You will not even gain a 1-2% difference going from 4GB to 8GB unless your using swap with 4GB. The ram is for the ramdisk. Which acts as a partition on the system (C:/ this will be D:/). The average Read/Write of a SSD is 300-500MBps. The average Read/Write of DDR3-1600 ram is 5000/5000MBps. When you play Diablo 3, all the game-data, music, monster animations, etc are stored in the MPQ files (Diablo III\Data_D3\PC\MPQs). This data is too large to be stored in ram, so its stored on disk, and loaded into ram when needed. Reading the data off the disk into ram incurs multiple penalties. First the disk must be idle as the read head can only do 1 thing at once, reading from a disk is not multithreadable. Then the speed of the read is not that fast. When you run the game off your ramdisk (D:/ drive), these reads first of all dont need to align the read head of the disk, so the access time is much faster. Second the transfer rate of 5000 up/down MBps is blazing fast, the Diablo 3 MPQs are about 10gb in size. It would take 2 seconds to read all of them. Using a fast SSD would take 10, and if reading small parts of multiple MPQs randomly, would take MUCH MUCH longer on an SSD then if it were in ram.
The difference is most noticeable on joining new games, black screen delay before a cutscene or starting up the game for the first time.
