Howdy, for my birthday 2010 I am going to be creating a custom igaming computer using a budget regarding about 2000$.What I want to know, is how do i get one of the best for our buck on this money Relating to never made a personal computer before, but I am getting guide from several friends.Please help myself out:)

Here’s what I would by as budget:

Motherboard:Asus Sabertooth P67 Rev SEVERAL.0
One:Intel Central i5 2500K Sandy Bridge BOX
Much cooler:ArcticCooling Fridge XTREME rev.2
MEMORY:Corsair DDR3 8192MB (2 x 4096MB) 1600MHz CL9 Glowing blue Vengeance

POST didn’t fuss adding the keyboard, any mouse as well as speakers, although I understand they are important for a new gamer although I have no idea if you currently have those and also not, plus it’s likely you have some individual preferences during this matter.But that PC will be great and within your budget.:).
