While credit cards and debit cards may look almost identical, not all plastic is the same.
"It's important that consumers understand the difference between a debit card and a credit card," says John Breyault, director of the Fraud Center for the National Consumers League, a Washington, D.C.-based advocacy group. "There's a difference in how the transactions are processed and the protections offered to consumers when they use them."
While debit cards and credit cards each have advantages, each is also better suited to certain situations. And since a debit card is a direct line to your bank account, there are places where it can be wise to avoid handing it over -- if for no other reason than complete peace of mind.
Here are 10 places and situations where it can pay to leave that debit card in your wallet:
1. Online
"You don't use a debit card online," says Susan Tiffany, director of consumer periodicals for the Credit Union National Association. Since the debit card links directly to a checking account, "you have potential vulnerability there," she says.
Her reasoning: If you have problems with a purchase or the card number gets hijacked, a debit card is "vulnerable because it happens to be linked to an account," says Linda Foley, founder of the Identity Theft Resource Center. She also includes phone orders in this category.
The Federal Reserve's Regulation E (commonly dubbed Reg E), covers debit card transfers. It sets a consumer's liability for fraudulent purchases at $50, provided they notify the bank within two days of discovering that their card or card number has been stolen.
Most banks have additional voluntary policies that set their own customers' liability with debit cards at $0, says Nessa Feddis, vice president and senior counsel for the American Bankers Association.
But the protections don't relieve consumers of hassle: The prospect of trying to get money put back into their bank account, and the problems that a lower-than-expected balance can cause in terms of fees and refused checks or payments, make some online shoppers reach first for credit cards.
2. Big-Ticket Items
With a big ticket item, a credit card is safer, says Chi Chi Wu, staff attorney with the National Consumer Law Center. A credit card offers dispute rights if something goes wrong with the merchandise or the purchase, she says.
"With a debit card, you have fewer protections," she says.
In addition, some cards will also offer extended warrantees. And in some situations, such as buying electronics or renting a car, some credit cards also offer additional property insurance to cover the item.
Two caveats, says Wu. Don't carry a balance. Otherwise, you also risk paying some high-ticket interest. And "avoid store cards with deferred interest," Wu advises.
3. Deposit Required
When Peter Garuccio recently rented some home improvement equipment at a big-box store, it required a sizable deposit. "This is where you want to use a credit card instead of a debit," says Garuccio, spokesman for the national trade group American Bankers Association.
That way, the store has its security deposit, and you still have access to all of the money in your bank account. With any luck, you'll never actually have to part with a dollar. (full Story)
Another boost in performance is the result of the larger 12MB L3 cache on the processor (up from 8MB on the Core i7-975). The L3 cache is a holding cell for the data the CPU is processing, and more L3 cache means that the CPU has to access the relatively slower DDR3 memory less often. The cache will help speed up single-threaded tasks like gaming, though as seen in our testing, the choice of GPU is still more important to the hardcore gamer..
Not surprisingly, the Core i7-980X will show up on gaming PCs first, like the Maingear Shift and Falcon Northwest Mach V (Core i-980X). Well-heeled gamers are exactly the type of consumer who will crave a $6,000+ system with a $1,000 processor and $1,500 worth of graphics cards. Gaming system builders have a lot of experience combining the extra overhead in the CPU's thermal envelope with liquid cooling to bump the stock 3.33GHz clock speed up to as much as 4.3GHz while running heavy loads. The overclocked processors still cool down while idle, so they're not running at full speed all the time.
So, is it worth it? Yes and no. Our performance tests with the Falcon Northwest Mach V and Maingear Shift show a significant performance bump in multi-threaded tasks like CineBench R10 (a doubling of performance from the mid-range Core i7-870). There's also a significant speed bump for the PCMark Vantage test, which is multi-threaded and measures day-to-day tasks. However gaming tests still depend more on the graphics you put into the system, with the credit going to multi-GPU systems rather than multi-core CPUs. The multimedia tests are starting to reach a plateau of diminishing returns: while the scores are still getting faster, having an ultra-fast quad core and SSDs are "enough" for tasks like Windows Media Encoder and PhotoShop CS4. Throwing two more cores at the multimedia tasks won't help at this time. Maybe they will help when Adobe releases CS5; time will tell. (story Link)
Following a successful run with the codenamed R700 family of GPUs, which was originally released back in June 2008 as the Radeon HD 4000 series, AMD is launching the highly anticipated R800. Debuting to no one's surprise as the ATI Radeon HD 5000 series, on our test bed today we have a reference HD 5870 graphics card packing some 2150 million transistors and produced on a 40nm process.
The new Radeon HD 5000 series is said to deliver around 2x more performance than previous generation Radeon cards, and brings DirectX 11 support to desktops for the first time. Even while Nvidia is downplaying the latter, AMD sees it as a great advantage and expects DX11-capable games to start shipping before the end of the year.
Nvidia will also support DirectX 11 on future hardware of course, but the way things are going it looks as though we'll still have to wait a few months before their response to the new Radeon HD line arrives.
AMD's pricing strategy with the Radeon HD 5000 series will be quite interesting too, as for the first time in a long while the company will be looking to take the performance crown from Nvidia. Previous generation ATI graphics cards have been unable to compete with the fastest Nvidia solutions, forcing AMD to heavily discount their products in an effort to deliver better value.
In the end the Radeon HD 4850 was competing with the much older GeForce 9800 GTX, while the Radeon HD 4870 ran somewhat unopposed at $299. At this price point the 4870 delivered an impressive level of performance, though it was overshadowed by improved GeForce GTX graphics cards over the next 12 months.
The new Radeon HD 5870 is in a very different position, though. This time around it looks like AMD is not going to be forced into a pricing war as easily -- at least not yet anyway. So for now the HD 5870 makes its debut with an MSRP of $380, while the Radeon HD 5850 is also arriving today priced at around $260.
This makes the Radeon HD 5870 roughly $120 cheaper than today's undisputable performance champ, the GeForce GTX 295. It also makes it almost twice as costly as the Radeon HD 4890, however, which begs the question: is the Radeon HD 5870 really that much faster? Today we finally get to find out, as we will be comparing AMD's latest and greatest against every single high-end graphics card released over the past year. (Full Story Link)
