Arbico’s i5 7668 Pro desktop PC is very close to the Chillblast Fusion Black Ops in specification, yet it lagged somewhat behind that machine in our performance benchmarks.

Arbico’s i5 7668 Pro desktop PC is very close to the Chillblast Fusion Black Ops in specification. Both use Intel’s 2.8GHz Core i5-760 CPU, the Asus P7P55D-E motherboard, 4GB of DDR3 RAM, a 1TB hard drive and the familiar 23.6in HKC 2249A monitor. The two PC vendors have even selected the same Asus ‘DirectCu’ version of the ATI Radeon HD 6850 graphics card with 1GB of video RAM.

As we noted in our write-up for the Fusion Black Ops, this card has had its core clock speed fractionally increased and benefits from a superior cooling solution. Had any of the PC vendors here supplied a standard HD 6850 card, we would expect to see slower framerates than the Arbico i5 7668 Pro desktop PC.

With the same components selected, we would expect to see these two Windows 7 PCs tie neck-and-neck in our performance tests. In fact, the Arbico i5 7668 Pro desktop PC scored 133 points in our WorldBench 6 processing speed test, while the Chillblast took the chart lead with 138. The Arbico also fell somewhat behind in our gaming tests, although the difference is only slight.

Should you want to boost the gaming potential of this machine, the Asus motherboard supports the addition of a second graphics card. However, CrossFireX enthusiasts would do better buying a motherboard that supports both slots at the full x16 speed. This board also adds two USB 3.0 ports and 6Gbps SATA to the Arbico i5 7668 Pro desktop PC.

Housed in the same Cooler Master case as the Palicomp, the Arbico i5 7668 Pro desktop PC looks smart and tidy, and offers ample space inside.

The Arbico i5 7668 Pro desktop PC doesn’t come with any external speakers, although on paper it improves on the Chillblast’s 500W power supply unit with an 850W AvengePower.

Arbico’s i5 7668 Pro desktop PC is very close to the Chillblast Fusion Black Ops in specification, yet it lagged somewhat behind that machine in our performance benchmarks.

Budget PCs buying advice

Processor: Intel’s latest naming scheme is confusing: if you want a quad-core PC, look for a Core i5-700-, 800- or 900-series CPU; the newer Core 5-600-series chips are dual-core.

Quad-core chips offer greater multiprocessing capabilities, but the higher clock speeds of dual-core chips mean they can run single-threaded applications faster. Non-gamers should note that their integrated graphics chips will allow them to play full-HD video without a discrete graphics card.

Intel’s 2.8GHz quad-core Core i5-760 is the current king of the £501-£750 desktop PCs category and is compatible with the most up-to-date motherboards and DDR3 memory.

AMD’s quad-core Phenom II X4 920, 940 and 965 also offer good value for money, although they can’t match the Core i5 in our tests.

Some AMD processors contain hidden extra cores that can be enabled in the Bios. Ensure that any tweaks are backed by the vendor.

Memory: If a fast CPU speeds up your PC, a large bank of memory stops it from slowing down. Get the most out of your CPU with 4GB of RAM. You can get by with 2GB, however.

Core i5- and i7-800-series CPUs use DDR3 memory rather than DDR2, but there’s no need to buy the chips in threes as you do with i7-900-series systems.

Storage: Digital media will quickly fill a reasonably sized hard drive; buy the biggest you can afford. At least 500GB should be expected at this price point.

Consider using a pair of smaller hard drives rather than one large drive – a terabyte (1TB) is a huge amount of information to lose in one go.

With prices falling all the time, you may find a solid-state disk (SSD) affordable. The extra performance provided can transform your computing experience, but make sure you get one at least 60GB in size and install your programs on a second drive if you want to avoid running into drive-space problems.

Your DVD drive should write to the KR formats at 18-speed or better. Eight-speed rewriting is good; if you want to copy up to 8.5GB at once, look for fast DVD+/-R dual-layer drives. Blu-ray readers are becoming more affordable, but they’re still quite rare at this price.

Display: Note that 19in screens offer a lower resolution than 20in/22in monitors; 22in models display larger icons. Newer 21.6in (16:9) flat-panels are capable of displaying full-HD content, but onscreen elements will be even smaller. You will now find many budget 23.6in displays available at this price.

A DVI or HDMI connector will provide a considerably better image than a VGA port; if you want to connect additional devices, you’ll need at least two.

Finally, look for a good response rate: 8ms or below is fast enough for games.

Graphics cards: We test graphics framerates with Crysis and Stalker: Call of Pripyat. The latter can benchmark DirectX 11.0-capable graphics cards. Although 25fps is enough to make a game playable, you can set your sights higher at this price point – look for 50fps.

Current pricing will limit you in this area, but ATI’s new Radeon HD 6850 offers excellent performance for the money. Cut back on other components and step up to a Radeon HD 6870 if gaming is very important to you. nVidia’s GeForce GTX 460 also offers good performance.

nVidia cards offer support for realistic object interactions in games supporting PhysX and are able to display 3D content.

If you don’t play games at all, consider using only the integrated graphics of Intel’s Core i5-600-series processors.

Power supply: A large power supply unit (PSU) is less vital at this price point, but look for a model with a full set of SATA and PCI Express connectors to make later upgrades easier.

Sound card and speakers: Most motherboards in this chart category depend on onboard sound. To get surround sound, look for a 5.1-channel system (five speakers and a subwoofer).

OUR VERDICT

Despite an almost identical specification, the Arbico i5 7668 Pro desktop PC was beaten in our performance tests by the Chillblast. Given that it also lacks that machine’s external speakers, we are unable to recommend this (still very good) desktop PC over the Fusion Black Ops.
