^ CX430 is enough for any single gpu system on an intel i5... it's a CWT. It's not a bad PSU but as long as you don't run a ton of accessories, it will be fine - and that's more a problem with the low quality short circuit protection, no the wattage.
Remember, Quality > Quantity. And the cx430...
When you go TKL you never go back.
Full size boards are just awkward. With a TKL, you can have both your arms straight out - they will naturally fit on wasd/asdf and your mouse. With a full-size board, your mouse hand will awkwardly be out to the side a bit, or you have to spread both arms out...
The reason timings are more appreciated by AMD, and that speed matters less for AMD than intel, is because the memory controller on them is terrible (hence the guy saying it made a difference going to 7 from 9 on a thuban, ie 1090t).
AMD controllers, as I understand it, cannot go above 1600mhz...
