Graphics cards

Getting the most from your card

Another element that may be important to some buyers is the overclockability of the graphics card. Overclocking refers to pushing a particular piece of hardware, be it RAM, CPU or Graphics card, past the clock speeds available out of the box. Most hardware can be overclocked to some degree, with the limiting factor being the temperature of the item.

Gainward's Golden Sample indicates strong overclocking

Depending on the brand of card you buy, the cooling you have in place and the quality of the memory it uses, you may be able to push the card well beyond its standard specifications, with some cards overclocking to speeds past that of the next tier up. Several companies even guarantee their cards to overclock to a certain level, so if you are interested in pushing your PC that little bit further, and can afford to spend a small amount more, be sure to look out for those. You can also shell out a bit of extra money and buy some third party cooling devices for your card, including fans and heatsinks, which may increase the level to which you can overclock, but this will obviously cost more, and may also be louder than any out of the box cooling available.

It is important to be aware that overclocking can damage your hardware, and many manufacturers will not honour the warranty if it is damaged in this way, so overclock at your own risk.


If you're serious about getting the best graphics cards, benchmarks usually provide a better indication of performance than the specifications ever will. There are a number of sites that regularly run reviews of graphics cards, including comprehensive performance benchmarks. We recommend:

HP OfficeJet 250 Mobile Printer

The HP OfficeJet 250 Mobile Printer is a great device that fits perfectly into my fast paced and mobile lifestyle. My first impression of the printer itself was how incredibly compact and sleek the device was.

Wireless printing from my iPhone was also a handy feature, the whole experience was quick and seamless with no setup requirements - accessed through the default iOS printing menu options.

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
