I sent a message to Kryo about the RAM. And I'll look for a computer with a about a 3GHz processor. I don't know anything about graphics cards or what to expect. If there isn't any set requirements for this yet it would still be nice to have a suggestion to what to, or not to have.

Try and get an NVIDIA card in the "GTX 700" line. The 760, 770, 780 and the Titan are all great choices, with the earlier two being pretty affordable for their cost. Alternatively, if price REALLY isn't an issue, you can wait a bit for the "GTX 800" line of cards or buy a Titan Black. These cards should be able to handle most, if not all, games at their maximum settings without breaking the 50% usage mark. ASUS is a good vendor to buy these from, as their sub-variants are usually somewhat superior and more reliable in my experience.
I also recommend getting 16 GB of RAM, because it's pretty cheap and it will help you with larger games that eat up memory, though 8 GB is all you really need.
Remember to get a good CPU, preferably one which can overclock to over 4 GHz. If you go with Intel (You should) avoid the i7 and i3 line of chips, as they are not optimized to use for gaming (Most games can't use the 8 cores of the i7, and the i3 models are not strong enough for modern games.) Get an i5 CPU with 4 cores and overclockability, as it will provide you the best tradeoff between expense, power, lifespan and utility. The card I use is an i5-4670k, which can demolish pretty much everything without breaking a sweat at a cost of 240$.
There's much more to cover, but that's vital stuff.
