Trends Audio’s UD10.1 is a digital audio converter that can do more than just connect to a PC. With its extra, professional-level outputs the UD10.1 might be the AV accessory you’ve been searching for.

If you're in the market for a new high-end PC, it's worth spending your cash on a platform based on the Core i7. This Extreme Edition CPU will also let you overclock it reliably, and allow you to get close to 4GHz while only using an air cooler.

If you're a firm believer in the 'behemoth GPU', Sapphire's Radeon HD 4850 x2 will do little to sway your opinion. While it performed solidly enough in our benchmarks, it failed to match NVIDIA's single-GPU GTX 280 offering. Nevertheless, it remains a good option for any self-respecting Radeon fan with a penchant for monitors.

The B2 Stealth Bomber is a flawed gaming chassis let down by poor cable management, a crammed interior and myriad design glitches. If you don’t intend to regularly upgrade your system, it might be worth considering for the cool aesthetics. But only just.

The Sapphire Radeon HD 4870 TOXIC is a cooler and slightly more powerful alternative to the standard HD 4870 board. It will mainly suit DIY overclockers who want to get the most out of their system without turning their PC into a furnace.

The HD 4550 is a good, affordable option for high-def movie playback and occasional gaming. However, unless you’re on a shoestring budget, we’d recommend the HD 4670 instead. It offers a vastly superior graphics performance for a slightly higher premium.

Put simply, if you need a graphics card that’s able to play most recent 3-D intensive games at reasonable performance levels, EVGA’s latest 8800GT variant is a good choice at a reasonable price.

Although this card is not bad in its own right, it lacks the punch-per-dollar provided by ATI cards in the same price-bracket. But if you're unwilling to leave the NVIDIA camp and are looking for a moderately well-performing budget option, the EVGA GeForce 9800 GT (512MB DDR3 PCI-E) is worth a look.

The Sapphire HD 4670 is an entry-level graphics card that casual users will be sure to love. Like its midrange and high-end siblings, it offers an exceptional performance for the asking price. Another Radeon winner.

The ATI Radeon HD 4670 is a mid-range graphics card decked out in entry-level clothing. While it lacks the sheer processing power of its more expensive siblings, it still packs a pretty impressive punch. With an RRP of well under $150, it’s one of the best-value cards on the market.
