KEYBOARD (I have a mouse already)
SOUND CARD (I think I need this- do I?)
Network antenna (or whatever that thing that connects to wifi is called)
MONITOR (20" would be nice)
As you can see by what I already have picked out, I'm looking for budget parts. I'm hoping to build this in the $350-500 range.
And all of the parts need to both be compatible and work with the case.
But as a rule of thumb, if you're even halfway serious about gaming, $100 is about the floor for where you should be looking at video cards. HD 6770, GTX 550 Ti - around that range are the cards that are not top-of-the-line but will get you by for moderate intensity gaming. GPUs in the $50 and $60 range are generally not intended for gaming and will give you a slideshow except at low resolution and low detail.
Okay, you have a good budget start there the Phenom 965 black is a good processor and will play happily with the AM3+ mobo.
The PSU is a little overkill but it is a quality unit and the price is good.
Couple of questions for clarification; 1) Case size - you have a micro ATX motherboard chosen so your options for a case are; Micro tower, mid tower and full tower (mid towers are the most prevelent and most used by home builders). 2) Do you want surround sound? If not, the motherboard has built in sound (which works adequately unless you're an audiophile).
For your stated purposes, the graphics card (although on the very low end) should work fine.
Note, I used the NewEgg links only because they have excellent descriptions of the products - you should by no means take it as meaning you should purchase from them (although they do have good prices).
Optical drives come down to your desires, Blueray? DVD?. I personally opt for the cheapest optical drive I can find (DVD writable, usually ~$20). No tricks to this one, one size fits all (5 1/4" bays that is).
As mentioned by others I would seriously consider working out a budget for a stronger video card. Yes the card you have will get the job done, but as a primarily Runescape for many years, I know that these kinds of game companies sometimes decide to do a graphics update that can obsolete your budget computer overnight.
At bare minimum price, this would be a very competent gaming machine:
Total- $635 You can knock off 30 dollars from this figure by using the case you were looking at instead of the HAF 912 I recommended. And cut some corners on the RAM, maybe the video card just a tad. (My build is a boiler plate build I have saved- it can be tweaked as necessary) Windows7 costs about 100 dollars more, send me a PM, I can help you with that.
Oh, if you're looking for oldies, I can do you a really nice build in that budget.
Better than that barebones. (keep in mind your barebones has a lousy onboard video, even for oldies, and a questionable quality power supply)
I have a laptop with HD3000 graphics, its terrible, struggles even with Facebook games.
CPU+ graphics- Llano 3870K $120 http://www.newegg.com/Product/Product.aspx?Item=N82E168...
That would be better than the Athlon II barebones kit yes, just keep in mind the GT 520 is a pretty weak video card, probably not even as strong as the Llano, either way, it should be sufficient for your purposes. That kit comes with again, probably not a very good power supply.
