Not all CPUs need four cores and ludicrous speed to impress. This low-end Intel chip is one of the best bargains we’ve seen. It may have the Pentium name, but it’s actually a pared-down Core 2 Duo, with just 1MB of L2 cache and an 800MHz front side bus. If that all sounds a bit weak, look at our Luxury £599 PCs Labs to see just how far this versatile little thing can be overclocked: it may come at 2GHz as standard, but with a normal stock cooler it can very easily be pushed to a massive 3GHz, putting it on a par with some of the vastly more expensive processors. And at a cost of just £50, this flexibility and performance potential make it one of the best processor deals of the moment.
