Samsung monitor, Razer kb/mouse. 30w speakers.
In terms of the keyboard and mouse, they were offering them on amazon UK as a package with the mat, and I liked the look of the flat keys as I'm a taiko player on osu! - I had also been previously using a laptop to play, so I'm used to using flat keys.
Tower unit. Contained within i7-920 (Bloomfield) & 260 GTX.
It would seem to be through hours of research that basically Intel is better than AMD for general use and multitasking... vice versa for gaming. Since what I use my computer for is mostly osu! and video rendering, I went for Intel.
