System Builder Marathon, September 2009: The Articles
Here are links to each of the four articles in this month’s System Builder Marathon (we’ll update them as each story is published). And remember, these systems are all being given away at the end of the marathon. After some delay (sorry folks), the contest is ready to be entered. Please visit the entry page, here.
Day 1: The $650 Gaming PC
Day 2: The $1,250 Enthusiast PC
Day 3: The $2,500 Performance PC
Day 4: Performance and Value Dissected
Introduction
One thing sorely lacking from our System Builder Marathon (SBM) articles has been AMD, and that's not because we don’t like the green team. Putting most of our focus into overall system performance caused us to overlook some of the excellent value AMD offers almost exclusively in the gaming market. Thus, we’ve added a couple of titles for our game benchmark tests where AMD really shines.

But AMD’s competitive prices don’t extend only to gaming processors and graphics, as the company also has a thriving chipset business. You certainly won’t find a northbridge with 42 PCI Express (PCIe) lanes from Intel, and otherwise similarly-equipped X58 motherboards come with an approximate $100 price premium.

| Bay Adapter | Vantec MRK-250FD 3.5" to 5.25" adapter | $13 |
| Total Cost | $2,490 | |
We were even able to put the money saved on the motherboard (as well as a few other areas) into storage, adding two 80GB Intel X25-M solid-state disk (SSD) drives for super-fast load times and upgrading the optical unit from a Blu-ray reader to a BD-RE writer, all in an effort to satisfy a multitude of reader requests. Let’s take a closer look at how it all went together.

- It’s Ready To Fight

The last build was a bit too odd for me but this one seems like a very nice chose of parts and on a larger screen set up makes a lot of sense the loss of i7 for AMD only build was a bit sad but the addition of those great SSD kind of makes up for me along with the nice chose of case and cooling. That case looks like it is very nice to work on.

Check your sources because you have it wrong
CMPSU-850HX ATX12V 850 90.38% Gold
Newegg says differently. I did check sources.

I guess you just can't believe everything you find on a brands site.
You going to believe newegg a site that is known to make mistakes in labeling products over the actual official site of the group that freaking does the testing and certification

It's gold...
Anyone who wins this has an awesome rig on their hands!
Either water cool the GPUs or use a case with better air flow. Perhaps 90C is within spec (although I'm not aware of any published official max temps for 4890s)but it doesn't seem like a good idea to me.
What's with the limited choice for a case anyway? You seem to want to experiment? CM Storm Scout has handles, or Lian Li Lancool has great air cooling and radiator hose grommets.
I did like the inclusion of the Swiftech kit.

So...I guess it's really Gold?
(sarcasm)
80 plus is an independant rating site, the 850HX was upgraded to Gold status so unless you're using an old unit you should be fine.
This editor never uses external radiators because they're too easily damaged, ugly, and make transportation difficult. The only choice not mentioned was the HAF932: There's one in the lab, it's enormous and cheaply built.
Also, there's absolutely nothing wrong with the ventilation of the case used. It's remarkable. It's darned near perfect. The GPU's run hot for two reasons: HD 4890's are horribly inefficient and there's not much space between them.
The other option would have been to face the PSU fan towards the cards so it could draw warm air away from them.
I would take this over your last $2,500 Intel system no doubt!
This thing is a work of art.
Excellent work.
Wait wait wait... why would I want a phenom when i have a i7? I don't know, but this system is that cool.
I love the case used on it too. Tri-4890, 2x80GB SSD etc. even on a 2.5k budget is admirable.
Making me wonder were all the money on my build went...
Also nice to see a cheap motherboard being promoted. I paid over $300 for my mobo, and I regret it (good overclocking mobo... crappy overclocker cpu). >_<
Keep up the good work.
