I just did a budget pc build for gaming. And since you said your going to piece it together why not pop for the Black Edition one. You already posted 1 item that was $139. The AMD FX-8120 Zambezi 3.1GHz Socket AM3+ 125W Eight-Core Desktop Processor FD8120FRGUBOX
might be right up your alley. It's $20 more plus its easily overclockable.
motherboard: I'd say the ASRock 970 EXTREME3
or even the GIGABYTE GA-970A-UD3 AM3+
The PSU I'd also not suggest that one. They tend to lack. I got a sivlerstone 850watt for about $100 but this ensures I know it will last more then a few months.
Graphic card: Today actually I got ahold of a MSI 460GTX for $75 off ebay. And atm there is one up for 60 bid. Its over clockable and is very quiet. I get beast mode on BF3 with it. The ones you linked at basically really low end cards. They will be OKAY at best but will put a strain on if you try to push a newer game.
SSD: a 68gb drive is good. Its fine for running windows and a few key programs off it. I'd suggest grabbing a 1tb HDD for storage and other progams. Like the new Guild Wars 2 is 20gigs. It's better to have them on the HDD while the SSD runs the OS.
Case: SWEEEEET looking. I didn't need all the bling so I went with a Coolermaster 922 XM case with 4 200mm fans to keep it cool.
CPU COOLER!!!: Most important part. A stock one is loud very loud. I saved extra for my budget build and actually bought a Noctua 6 Dual Heatpipe with 140mm/120mm Dual SSO Bearing Fans CPU Cooler NH-D14
. This thing is BEAST. I tried and tried, I can't get my pc over 45c even in the summer. There are others that are similar. The Thermalright Silver Arrow SB-E Dual Fan Universal CPU Cooler
Or even if your into the watercooling enclosed type the Corsair Hydro Series H80 High Performance Liquid CPU Cooler
would do great.
Lastly: A budget build doesn't need to be junk parts cause you just wanna go cheap. That extra 20 or 30 dollars on that one piece can be the best thing you ever did. And it will let the pc last that much longer till you have to upgrade. Hopefully this stuff helps.Edited by CyberDemonz101 - 9/11/12 at 5:14pm
