Special figuring specifications for computer games online

This is a poster I made based on the question posed by one of the brothers cafe operator (whether it be the owner of the cafe employees ato). Questions submitted: which is better PC or upgrade the old continue to buy sell new and why for certain game2 it often LAG / dotted ??? 

ok just give me the bottom line: 

to the question which is better ato upgrade sales continue to buy new long ?

1. Requirement if you want to upgrade certain parts there are a few things to note 

• Specification of the game itself. Try to check the recommended specs from memory, VGA, Processor, etc. 
• support to the hardware itself can still be found if the spare parts or spare part is already hard to find increasingly difficult to find if it is better to buy a new one so if there is damage it easier to find spareparts for time efficiency and price

2. why for certain game2 it often LAG / dotted ??? 

• VGA, because this is the main task of processing the graphic. Although the onboard VGA / default of the motherboard is great but still in need VGA External why ??? because the onboard VGA own it her duty to help applications that do not require too much power while the external VGA has been specifically designed for advanced needs such as design, rendering, play games with high quality course is supported with adequate power, etc.. 
• There are options 64bit external VGA DDR3, DDR3 128bit, 256bit DDR3 Which of the three great ??? equally good in fact differentiating only in terms of pixel depth or color (comments only if this statement is not true) to do the purchase is the price that must be considered !!! why ??? because the price also affects the efficiency of budget / financial conditions eg 1GB DDR3 VGA brand X1 64bit with price 350rb while VGA 1GB 128bit DDR3 Brand Y1 at a price 420rb. Surely I will take the brand because of the difference Y1 70rb whereas if you buy 3 Pcs up may be able to piece 20-30rb depending seller willing to give pieces barapa 
• Memory / RAM. For online and offline games. For there are certain games that require memory / RAM above 4GB I recommend using a 64bit operating system (can read up to 16GB of RAM, while the 32-bit can only read up to 3GB, the rest will be put into the graphic). 
• Select DDR2 or DDR3. I take the DDR3 menyarakankan! Why ??? because DDR2 is now on the market, although still expensive comparable to 4GB DDR2 2GB DDR3 to get (if you do not believe check and ask yourself at the store). The difference is in the speed of rotation of the data
• Before buying check the slot on the motherboard is provided for DDR3! Why ?? because of personal experience never buy DDR3 memory on the motherboard apparently no slot although a cursory look the same but the difference in slot / pin his 
• may I mix it up as 4GB of DDR2 memory with an external VGA 512MB 128-bit DDR3? Honestly I myself do not know the effects of both of these things because I have not tried it but I suggest equated only if DDR2 memory should use the external VGA DDR2 although there are some types that support external VGA DDR2 & DDR3 
• to issue the motherboard, processor and power supply that follows the course 
• to the problem there is that connection speeds suggest use 2MB, 3MB, etc. depending on the amount of the computer itself if the more it is necessary in view also the speed of the connection

so that I can give the analysis may be helpful, actually want to provide an analysis of proxy caching and server as well as a handy but since have not been getting the science and practice are real then I'm afraid can not give his analysis does not match what is expected.
