Powerful, well price and a worthy addition to the A-List. The PacStar Core i7 is a PC we wouldn't be unhappy to take home and spend the weekend gaming on

A beautifully designed, powerful system that almost no-one will be able to justify buying. If your IT department can find the budget to put a new Mac Pro on your desktop, you're lucky indeed

Raw power and gaming prowess plus our a-listed monitor: this is a fantastic system, but the price is a deterrent.

If we were looking for some of the highest benchmark scores we could attain than we'd highly commend this machine

A monster PC thanks to some very high-end components. But it’s noisy and expensive.

Fantastic design and highly-configurable power make this XPS useful, desirable and good value.

A very fast, well-built high-end PC. But a few niggles and high price keep it off the A-List.

Quad-core makes it powerful and good value at the price. Noise and stability suffer though.

Nvidia’s 8800 GTX graphics card is the crowning glory of this very-fast, great-value, PC.

Very fast, but the top-end components offer poor value in the face of competition.

A very fast computer with decent features at a great price, whether for gaming or an all-round powerhouse

The dual-core version of AMD's premium FX-series enters the game, and nothing can stand in its way.

The system as a whole looks great and we can't find a weak spot.

Look what four grand can buy you.

A good-value and very powerful system that will appeal to those seeking ultimate performance.

Aztec’s PC is a very different take on our $4000 PC A-List challenge.

We put out the call to Australia’s white box PC manufacturers for a good high-end $4000 PC and PC Express was the first to respond.

As far as performance is concerned, the Emagen Lightspeed XPS is a fairly competitive offering. It sits in the middle of the pack as far as price is concerned, but managed to sit at second to third place in most benchmarks - it even came top of the class in 3DMark05. The 3.6Ghz Pentium 4 certainly helped there. And the fact that it’s $600 cheaper than the Pioneer system also works in its favour.

The cheapest system to be submitted for review in our performance roundup, it just goes to show that even $4000 will get you a hell of a lot of PC for your money. PCQUEST has also opted to go with a CoolerMaster case, both for its attractive looks and functionality, this housing able to hold a massive five optical drives and four hard disk drives, erring on the side of more is better.

The iMac has always been a little more about style than function and the latest iteration is testament to this philosophy. The most noticeable thing about the iMac G5 is the massive 20 inch widescreen. It's a Big Mac. Geddit?
