PCSpecialist Vortex IV 770XS Review

The Windows Experience Index is a rather lacklustre rating tool, but it gives a rough indication of overall performance. This system scores very highly, limited by the graphics performance at 7.1.

A clean software install and pretty much what we would expect from the team at PCSpecialist. We installed START8 ourselves.


An overview of the system in CPUz and GPUz. The 4th generation Intel Core i7 4700MQ is a Quad core processor with Hyperthreading, to give a total of 8 logical cores. It has 6 MB of Level 3 cache. This processor is equipped with the capable integrated HD4600 graphics. You can read more on this processor over here.

To further enhance performance however, PCSpecialist have installed an Nvidia GTX780M, which is a high end discrete mobile GPU. It is built on the 28nm process and has 32 ROP's and 128 TMU's. There is 4GB of GDDR5 memory onboard running at 1,250mhz (5Gbps effective) – this is connected via a 256 bit memory interface. The core is running at 771mhz with a boost speed of 797mhz.

The memory is running at 1,600mhz with 9-9-9-27 1T timings.

We can tell by the specifications that this card will be able to handle the latest Direct X 11 titles with good image quality at full 1080p resolutions.
