Benchmarks - discrete GPU tests

We can also examine the effects of memory speed once a discrete card is used. Minimising the bottlenecks means using something meaty.. and they don't come much faster than a GeForce GTX 780.

Again, there's a small but consistent increase in benchmark performance, but it's highly unlikely that you'll feel it when playing games.
