Powering our 5755G was a 2GHz, quad-core Intel Core i7-2630QM processor, paired with 8GB of DDR3 RAM. These specs helped the laptop to deliver some very pleasing results in our series of benchmark tests.
In PCMark05, the 5755G delivered a healthy score of 9,049. With a score like that, you can rest assured this guy will happily munch through demanding multitasking and high-definition video streaming.
We also threw Geekbench at the laptop and were presented with a score of 11,391. By way of comparison, our packs a dual-core, 1.8GHz Core i7 and returned a far lower score of 6,285 in this test. We were still very impressed with the Air's nippy performance.
The laptop handled video encoding well, managing to encode our 11-minute 1080p video into 24-frames-per-second H.264 in a very quick time of 10 minutes, matchingpowerhouse gaming machine.
The 5755G will confidently turn its hand to some photo or video editing without shouting in protest, but don't expect it to run quite so smoothly if you're editing multi-layered raw images or chopping up high-definition video with a host of effects applied. If you do need some extra juice, a turbo boost function is available that overclocks the processor to 2.9GHz -- just make sure the fans can get to all the cool air they need to stop the processor from overheating.
Along with the powerful Core i7 processor, there's also an Nvidia GeForce GT 540M with 2GB of VRAM. This GPU managed to achieve a score of 8,962 in the 3DMark06 graphics benchmark test. The 5755G may not run the latest, most demanding games brilliantly, but slightly older titles should be fine.
We took Dirt 3 for a spin and were very pleased with its smoothness. The frame rate never dropped below around 35fps.
The 5755G's battery isn't exactly impressive, managing to last 59 minutes in our test. This test runs the CPU at a constant 100 per cent until the battery conks out, though, so you'll get a better time with less punishing usage. Acer reckons you can get up to 4.5 hours of use out of the machine, but we still wouldn't recommend straying too far from a power socket.
The Acer Aspire 5755G is no beauty, but it does offer impressive performance. If you're looking for a beefy laptop that will plough through your work, but isn't the type to shout about it, the 5755G is definitely worth a look.
