When it comes to performance, it's pretty much what you would expect from the latest-gen Intel processors paired with adequate RAM, which means it will handle an average daily workload with consummate ease. Though you can upgrade to Core i7 for £167, for most users the 2.5GHz, dual-core Core i5-2520M should be more than adequate, especially since it includes both Turbo-clocking and hyper-threading for up to four virtual cores.
As with most machines, 4GB of RAM is standard, with the option to upgrade to 8GB for a frankly ridiculous £190. Unfortunately, our review sample uses a regular 320GB hard drive rather than the standard 128GB SSD. Usually we would recommend going solid state every time, as not only will your laptop be noticeably faster, but also quieter, lighter, and it'll consume less power to boot. Unfortunately, when buying from Lenovo direct there's a £200 premium to pay for the SSD version, which is a tad steep. Still, if you have the money, you're not left wanting here. The OS of choice, meanwhile, is the 64-bit version of Windows 7 Professional.
Light gaming shouldn't present a problem - as evidenced by this ThinkPad's 50 frames per second average in TrackMania Nations Forever at medium detail and 720p - but most GPU-accelerated applications and remotely demanding games won't be too happy, as demonstrated by the unplayable 14.35fps average in Stalker: Call of Pripyat at the same settings.
