I am a computer building noob. Help?

I am building my very first desktop and I'm really nervous about purchasing all of the parts and of course, building a computer. Also It's going to mostly just be used for gaming, maybe some coding projects as well, but I'm perfectly content with using my school's servers for that. I am thinking about buying the following components:

Case: Rosewill CHALLENGER Black Gaming ATX Mid Tower Computer Case

Power Supply: Antec High Current Gamer Series HCG-520 520W ATX12V v2.3 / EPS12V v2.91 80 PLUS BRONZE Certified Active PFC Power Supply

Video Card: GIGABYTE ATI Radeon HD6850 1GB DDR5 2DVI/HDMI/DisplayPort PCI-Express Video Card GV-R685OC-1GD

Processor: Athlon II X3 455 Box AM3 3.3G 512KB 95W

Hard drive: Western Digital 500 GB Sata 6.0 Gb-s 16 MB Cache 3.5-Inch Internal Bare-oem Drives WD5000AAKX

Motherboard: GIGABYTE GA-78LMT-S2P AM3+ AMD 760G Micro ATX AMD Motherboard

RAM: G.SKILL NS 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-4GBNS


I still need to find a monitor, so suggestions would be great. I'm thinking in the $70-$150 range. I already have a logitech wireless mouse, wireless keyboard, and speakers.

opinions? changes? add-ons? Thanks for the help!

    Don't get that processor, it will bottleneck your GPU.

    Try this:

    And this looks like a decent monitor for your budget:
  2. Hey buddy! All the specs are pretty good, but except the video card. You would get more performance with a GTX 560Ti than a 6850. Also, the processor is pretty sub-par. I would get a Phenom II X4 965 or a 970 BE (BE = Black Edition btw :D ).

    I currently use a dual core AMD Athlon II X2 240, and a quad core such as the black edition Phenoms are a much better investment for gaming. If you want an Intel setup, go with the Core i5 2500K (remember, K = unlocked multiplier).

    The unlocked multiplier in Intel CPUs (K) and the Black Edition AMD CPUs (BE) are overclockable. This can mean two things.

    1) With an overclockable CPU, you can hold out on a CPU upgrade by overclocking your existing one

    2) If you're getting slow video encoding, then you can again, overclock it to get better results.

    Good luck with your build and if you need any help at all, we're always here :D
  3. Oh, and if I were you, I would get this:

    It's an Acer 24" monitor; pretty good specs if you ask me :)

    it's about £180 (which country are you in btw?)
  4. Thanks for all the suggestions so far! The processor was the hardest thing for me to find good advice on.

    I'm in the US. The 24" Acer is kinda out of my price range, but i'm liking the looks of the 23" Acer
  5. oops, I didn't realize there were guidelines to asking for help on building a computer in the forums. Sorry, here is the rest of that information (that I haven't already mentioned above):

    Approximate Purchase Date: This week, hopefully in the next couple of days

    Budget Range: $500-700

    System Usage from Most to Least Important: gaming, surfing the internet, watching movies, Folding@Home

    Parts Not Required: keyboard, mouse, speakers, OS

    Preferred Website(s) for Parts:,

    Country of Origin: US

    Parts Preferences: no preference

    Overclocking: Maybe? Not really a priority for me

    SLI or Crossfire: Maybe

    Monitor Resolution: undecided

    Additional Comments: specs of what parts I'm looking at are first post (+ suggestions given) Quiet is always a plus, but not a deal breaker

  7. Might want to check out a power supply calculator if you are considering doing SLI/Crossfire. Newegg has one on their site. 550w would be a little low if you are going to have two cards in there.
