The video game norm is to have 2 main threads and one GPU driver thread ("3 core utilization"). There'll be a whole bunch of secondary threads as well - but these consume negligible amounts of time (tops 5% or so totalling all of them), and many are only triggered in specific conditions - such as when the game needs to load new resources.
Consequently, even a 4 core CPU can have one of its cores idling pretty much at 100%, and there will nearly always be a fair bit of spare resources on the GPU driver thread, and often on the secondary 'main' thread. Far more than enough to run anything and everything in the background, save recording software in some configurations - backgrounds tasks simply aren't CPU demanding enough to care.
Skype does however the advantage for smaller, 2 or 3 man groups.
Or as is the use in WoW: Skype for Arenas, Mumble for Raids.
TPM requires (for Intel) support from the CPU - and some consumer level CPUs (notably the K series) lack that support. The extremely common 3570K for example - cannot use TPM. So in the above case, support is missing on the motherboard level, and on the CPU level. The newer Haswell variants (for both) still has the same inability.
Its always been more power efficient to employ more complex compression (more CPU work) over transferring more bits. Even for non-specialized CPUs this is true, never mind when you have hardware decoders.
I find eBooks a proper pain if you need to go back and fourth between a select set of pages. Theres no convenient or easy way to 'glance' on one page and then quickly return. In fact, you normally can't return at all. You can setup bookmarks, but the process is much slower and clumsier than done with a traditional book. You also cannot scan pages anywhere near as quickly when using an eBook versus a traditional book - for when you need to find a section of text (or a table) of which you are not certain its exact name or placement in the book in question.
eBooks due to their portability do work well though if you mostly need access to a single or specific section(s), where jumps are small or non-existant, or for sequential reading.
For fictional literature, eBooks are convenient. For learning materials, they're often poor.
Modern gaming computers are probably not pressed for disk real estate.
Well no, considering most gaming machines today are happily downgrading capacity for SSDs. And these machines very often have a HDD as well for bulk storage.
