Description

I built this rig last spring for my daughter as a basic gaming machine and it is working great.

This was the 1st generation of AMD APUs so I wanted to experiment with the dual graphics / crossfire with the highest available card the HD 6670. Overall the graphics work fine for Arkaham City, Portal 2, and GW2 though these are not too hard on the GPU.

In hindsight I would have gone for a Core i3 with a discreet GPU as there is not any great boost with the dual graphics.

Love the Fractal Core 3000 Case for smooth solid design and ease to work with. Kingston Memory is awesome and looks great.

Not a great fan of the Gigabyte board (Bios and Utilities are a bit of a struggle for example) but it works fine.

The hard drive is an old one from another build so nothing special there.

Got the OCZ CPU cooler and Power Supply B-Stock but they both work great and add to the aesthetics of the rig (shiny!). Other than that I added an LED strip from Ebay and rigged it to power off a 12v molex. Looks sweet under the monitor and has a remote to change color, dim, etc.

Edit: Benchmarks before and after the addition of the discrete HD 6670:

APU Only Baseline: Heaven Ave FPS: 9 Heaven Score: 227 3DMark P: 1025

APU Dual Graphics with HD 6670 CPU OC 3.375: Heaven Ave FPS: 34.8 Heaven Score: 876 3DMark P: 2041

Note: Updated to latest catalyst drivers May 2013 and performance shot up 57%. I think the drivers for the chipset favored the APU over 6670 but now works (just my theory).

thats the biggest heatsink ive ever seen LOL

Yup, it's big and shiny and looks great. Only knocked a few degrees off of the CPU temp but it's not extreme overclocking either :)

Shouldve done a build like this

WAY WAY WAY better performing

True, very nice build. I was on a bit more of a budget at the time for my build for < $400

OMG (except from the case) that is the exact build im getting but with an added 32GB SSD

Nice build, cable management isn't bad. Is it possible to hide the cables behind the back of the case? Also what is the light mod you use under your monitor?

pchurch submitter 3 Builds 2 points 23 months ago

Unfortunately the 8pin 12V was too short to route around the back of the motherboard. One downside of the Core 3000 case is the lack of a hole just about the MB for that cable.

For the LED mod I got a RGB LED strip from Ebay similar to this one: http://tinyurl.com/buddlep

They are powered by 12v AC adapters so I just stole a cable off an old AC (2.1mm DC plug I think) and wired it to a female molex to plug straight into a male molex off the power supply. The included IR remote allows for 12 colors, dimming, flash and color cycling. Cheap but sweet mod.

I wonder why it's a refurbished cooler. :)

Mincading 12 Builds 1 point 23 months ago

question about the LED strip, do u hook it up through black and red plugs? and also, did you cut the strip to fit the monitor?

pchurch submitter 3 Builds 1 point 23 months ago

No, yellow black. Yellow is the 12v red is 5v.

I did not have to cut it as I only got 30cm strip which fit. However, you can easily cut them (search YouTube) and can wire them in a daisy chain. Just be careful as you must observe polarity.

I have attached some new pics to the build with the wiring for the monitor LED strip.

This is FANTASTIC for the price! It's amazing how you were able to keep a sub-400 price point even with a monitor! Kudos!

you cant get good graphics by combineing one cheap card and intergrated but overall nice computer \

I think you should have got a 1tb drive for a couple more $

pchurch submitter 3 Builds 1 point 23 months ago

True, I recycled a drive for this one but would never buy less than 1TB now.
