HP once built its TouchSmart line using notebook components because they required much less active cooling. Limiting the number of fans inside the machine made it quieter. This TouchSmart not only uses a desktop CPU—Intel’s low-power Core i7-2600S, running at a stock 2.8GHz—but HP has also packed a discrete GPU inside this TouchSmart’s chassis. AMD’s Radeon HD 6550A might not be a barn-burner of a videocard, but it is vastly superior to the GPU core integrated into the Core i7. The Radon HD 6550A is DirectX compatible, but that doesn’t mean it will deliver a satisfying performance with highly demanding games. Playing Metro 2033 at 18 frames per second—in DirectX 10 mode—is not very satisfying. But no one will buy this type of a machine for gaming.
