In the current computer world FASTER is better.
The speed of a computer, how fast it will run your programs, is determined by the processor and RAM. All you need to remember is that the higher the number, the faster the machine. Buy a computer with the fastest microprocessor you can afford because at the end of four years it will be the slowest still available on the market. No matter how much you upgrade newer and better models will continually appear.
Most of us object to paying for something, only to find it worth much less a short distance down the road. Unfortunately, you might as well get used to it. You also might as well jump in when you need a system and look at the price as an investment instead of an expense.
Buy your computer-based on what you're going to do with it. If you've never used a computer before, you may take help from Yuva Tech Solutions technician for a consultant to know the suitable configuration for you. So you'll have to use your perceived needs and your budget as your rule of thumb. In that case, a good rule of thumb is to buy as much computer as you can afford and earmark ten to fifteen percent extra because you always end up spending more than you plan.
Another rule of thumb is to get the fastest PC you can afford. Computer speeds are measured in cores of the microprocessor and the higher the number the faster the microprocessor runs - at least in theory. There's a lot more to a computer's speed than just the microprocessor clock speed (like the amount of RAM, cache, etc.) but it's a good starting point.
Spend as much as you can comfortably afford. The more you invest, the longer your system will remain viable.
Technology continues to evolve at a rapid rate. Newer technology is always right around the corner, but this should not deter you from buying the system you need now.
Unless you have specific needs, you don't need to acquire the absolutely highest level of current technology. On the other hand, saving a few amounts by buying low on the technology curve is a false economy.
When you buy a desktop, one of your main goals is that you want it to be upgradeable. That means the following can easily be removed and replaced
Hard Drive, CD/DVD Drives, Memory (RAM), CPU, Video Card and Sound Card
If any of the above cannot be upgraded, you are buying into a closed system – like a laptop. All laptops are closed systems because their video, sound, and CPU generally cannot be upgraded.
