However, we recommend going straight for a higher-performing graphics solution instead of saddling yourself with such a low-impact hybrid solution. The side-port memory option does make a difference, but we can only recommend it if it comes at very little extra cost (just a few dollars). Most of the performance comes from AMD’s RV610-based 700 MHz DirectX 10 graphics unit.
In other words, it's something you cannot totally rely on; you'll have to get a dedicated graphics card for any decent gameplay.
