If you or someone you know is in the market for a new computer, then here are some helpful tips for what to look for as you shop.

1. Mind the Upgrades: Most computers offered in stores today are sold pretty much as-is, but a few box stores may offer some tempting upgrades.  Be sure to know which upgrades you might need before you arrive at the store, or you may find yourself buying an unnecessary extra component.  Most computers sold off the shelf are already configured with the average consumer in mind, but if you intend to use the new computer for gaming or even editing or producing your own home movies then you may have need for more memory or a better video card.  Search for those components online before going to the stores and you will have a better idea of the costs involved and whether or not the store is offering a good price for the upgrade or not.
2. Consider the Extended Warranty: Most extended warranties are sold as profit generators by the stores and for this reason have a pretty bad reputation among consumers.  But if you are spending more than $500 on a computer system, then a $50 or $75 extended warranty may be a wise investment.  If you are buying direct from the manufacturer then you may find their extended warranties to be a good bargain in order to secure maximum use of your investment over a 3 year period.  Be wary of store warranties as they may save themselves some money by placing most of the burden for the repairs on the consumer.  Ask questions if you are unsure and try to make the decision based on the replacement cost.
3. Make Sure the Computer Meets your Connectivity Needs:  If you plan to connect this computer to your TV or if you want to connect your camera or external devices to your new computer, then make sure you know what ports should be on the new computer.  All models should have plenty of USB 2 or even USB 3 ports.  If you need to connect to a TV find out if your TV needs a standard VGA connection or if it supports the HDMI connections supported on modern high-definition televisions.  Some external hard drives have the capability of using e-SATA for higher transfer speeds than standard USB drives.  And don’t forget to check the port placement on the new computer.  If that port you really need is only available on the back of the computer then you will need to be aware of this when you put the computer into its new home.

Be Careful of the Upgrade Treadmill:  If you’re a savvy consumer, you know that today’s top-of-the-line PC will be tomorrow’s budget box–and that you’ll be able to get the latest dream machine on the cheap, if you wait just a little bit longer.  Prices will inevitably drop, and upper-end performance will continue to improve. But if you persist in waiting for a mythical sweet spot to appear, you may end up stuck on hold indefinitely. Though you should certainly keep potential sales and price cuts in mind, your best bet is to decide exactly what you need, pick your acceptable price range, and go for it.
