Made a few builds depending on a few things:
BUILD 1
PCPartPicker part list / Price breakdown by merchant
CPU: i5, perfect for gaming and when OC you can hit 4.5GHz :)
Cooler: Good quality, not over kill and fine for first time overclocking!
Mobo: Great quality, now you might think why SLI ability? Read below
SSD: Great quality, enough for a game or 2 and OS
HDD: Plenty of room! For any confusion on reasons why I took stuff refer below
GPU: This is where it's kind of an issue... 970 is perfect for this and allows for an SLI relatively cheaply down the road if you wanna run triple 1080p or 1440p/2560p.. But there's a memory problem at the moment for all cards... So this is up to you, you can wait or go ahead with another build in here.
