Testing notes
Seven cards that span from £90-£165 are tested on the very latest NVIDIA and AMD drivers. We already know that the GTX 650 Ti Boost's performance will slot in between the regular GTX 650 and GTX 660 GPUs. What's of greater import is how it compares against AMD/Sapphire HD 7790 OC and the priced-reduced Radeon HD 7850 1GB.
