Let's look at the reasons people buy new PCs:

1. They don't already have one. With well over half the households in the United States now owning at least one computer, this reason, while still occasionally relevant, drives less and less purchasing.

2. The one they have doesn't work anymore. It's true -- over time PCs (particularly those that have suffered through operating-system upgrades) sometimes get so gummed up with multiple installations of software and corrupted system files and such that they just stop working right. And the hapless consumer realizes that for the money and time he could spend trying to fix the damn thing, he could probably buy a snazzier new computer. This used to be a surprisingly common occurrence, but Microsoft has gradually improved Windows over the years so that even the most wretchedly decayed PC today usually manages to limp along rather than going totally kaput.

3. Their old computer's hard disk has filled up. Each generation of software expands to fill the newer, bigger hard drives available. So if you've got an older computer that you keep cramming new software onto, you will eventually run out of space. (And then of course there are those 10,000 MP3 files you downloaded from Napster.) Sure, you could clean out your directories, or move the files to some other storage medium, or fuss with installing a new drive in your old box -- but it's easier to just take the 10 gigabytes from your old computer and dump them into your brand-new computer, whose 40-gigabyte drive will hardly feel what hit it. While I bet there are more computer purchasers out there who buy for this reason than you'd think, they are going to be reluctant to admit it, and they're going to feel guilty afterward: It just seems wasteful and self-indulgent -- like buying an SUV because you don't feel like changing the oil in your subcompact.

4. Their old computer isn't capable of doing something they desperately want to do. This is the industry's classic "killer app" scenario, in which the technological demands of some vital new business or consumer application drive massive new purchasing of hardware. The last "killer app" with any kind of legs was the Internet itself, and the cheapest PC on the market today can do a decent job of delivering the bounties of the Net to users. But if there's another "killer app" out there, Silicon Valley hasn't found it yet -- not even after the most extraordinary burst of venture capital investment in history.

5. Their old computer isn't as cool-looking/fast/capacious as the one they see in the ads. This rationale -- long a sales strategy for a computer industry that has refined planned obsolescence to high art -- is increasingly the only one PC makers can count on to fuel sales. Though Apple has had considerable success peddling cool looks as reason enough to open your wallet, most computer companies are still desperately pumping out spec sheets and number-laden ads to try to stoke our interest.

So does it means this is a good time to buy PC? well, from today to tomorrow, to next week and next year it will always be a good time to buy a new PC or upgrade if you really need them for some reason s like i stated above. But for Gamers, a top notch computer power is needed, same to developers and graphics publishers, but as home users that uses Computer just to write a word documents and checking emails, browsing the internet, a pentium 2-350 could do the job just fine as long as you dont run WinXP on it.
