Benchmarks: GPU
Computer Planet's decision to use a GeForce GTX 660 by default helps keep the total system price below £1,000, but of course 3D performance is somewhat limited as a result. As mentioned earlier, we're surprised to see that the GeForce GTX 660 Ti isn't an available upgrade option - to move up to another GeForce you'd have to pay an extra £150 for the GeForce GTX 670.
Then again, how much power do you need? The default GeForce GTX 660 is a capable card in its own right, churning out over 50 frames per second in demanding DirectX 11 titles such as Aliens vs. Predator.
And if you're playing older games, such as Just Cause 2, you needn't worry about quality settings at full-HD resolutions. The GeForce GTX 660 is more than capable of delivering in excess of 80 frames per second with 4xAA and 16xAF.
In-game performance is good, but we feel it perhaps could and should be better for a £1,000 machine. As far as gamers are concerned, it would most likely be beneficial to downgrade to a Core i5 processor and shift the savings over to a more powerful GPU. Though, remember, the ND 4000's choice of CPU is set in stone and can't be changed.
