Looking to build your own custom pc? Skarky Extreme publishes several Buyer's Guides which give all the parts needed for a new computer. There is the High End Gamer's PC where price is no limit, and a Value Gaming PC for the $1000 budget, along with regular guides on video card, memory, and cpu prices.

I've been using these guides for years and thought I would share. :)

Here is the link for Sharky Extreme.
