I'd check out Tiger direct if you wish to buy pre-made from various companies.
I'd stay intel based the link shows gaming pc's but you can browse around get an idea.
Here is a link:

If you want to buy from them go to"bing.com search tiger direct and you can save 8.3% Cashback with them. Saves a bit when orders start getting expensive.
