I'm building a computer but don't know what to get?

For the CPU as you stated, there is another and better performance processor. I would go with an i3 made by intel. Its a dual core with almost the same performance of a quad....Maybe cheaper to. The heat sync is important to. Make sure it fits the socket size. The mobo could be made by asus, one of the best mobos' around in my opinion. Make sure it has a pci express x16 slot for a graphix card. Then ram, "DDR3 that fits mobo. http://www.tigerdirect.com/ Brad

1. Pick out parts 2. Wait for delivery. 3, Unbox everything. 4. Start assembling everything together. With the mobo going in the case first, after the standoffs are screwed in. Decide what I want the computer to do (do I need powerful graphics, dedicated sound, etc). Decide how powerful a processor I need, decide between AMD or Intel. Pick a decent HS+fan for cpu. Decide on a motherboard compatible with my needs. Check the power and draw required by my components and buy a decent power supply with high enough Amperage (not Wattage). Pick the drives and peripherals. Find a case that will provide adequate cooling for my device. Put my credit card details

Newegg.com

600 bucks can get you a Dell at best buy. You're gonna need a few hundred more more some serious hardware. I have this, and I cost me a little over 1000. Intel i7 processor factory overclocked. (liquid cooling) Nvidia 450 GTS graphics (overclocked) 4 gigs ram 1 TB seagate Sata HDD. This is not bare minimum gaming nor is it the best.
