[:plant:] CPU & Mobo Selection

If you're going to be doing 3D, you want more threads to run, even if they are half-assed virtual threads. You'd still get a fairly significant performance boost, so i'd go for the 2600K unless there's a good reason to avoid it (apart from price, obviously). You'll be able to overclock with the stock cooler, but it's frankly rubbish in terms of long-term performance (the Intel stock round cooler is poorly machined and loves to get clogged by dust). I'd get an Arctic Freezer 7 Pro Rev 2. It's dirt cheap and totally silent except under high loads (when it becomes audible, but not what i'd describe as loud). As for motherboards, intense competition in recent years has resulted in even "value" boards being really quite good and fit for most purposes. Personally i've only ever used ASUS or Gigabyte boards but nowadays that's more down to habit than any real quality concerns. I've seen certain Gigabyte boards that come with an SSD (using the mSATA connection) that plugs directly onto the board. I think it's the Z68XP-UD3-iSSD so you might want to look into that.

Jam it back in, in the dark.
