System Builder Marathon, June 2011: $1000 Enthusiast PC

Benchmark Results: Crysis And Just Cause 2

The Crysis benchmark delivers some interesting results. At high settings, performance is very similar up to 1080p. But at 2560x1600, the CrossFire solution shows a sizable advantage.

When very high settings are applied, the single card is beaten across all resolutions. Having said that, the Radeon HD 6950 is capable of excellent performance at 1920x1080 at both of these settings, but without any anti-aliasing this game is very likely bottlenecked by something other than on-board memory.

Just Cause 2 obviously favors the current build’s dual-card graphics configuration, although there’s a strange hiccup at 2560x1600 using stock clocks. This is remedied when we apply overclocking, and the single Radeon HD 6950 is easily surpassed.

  • seller417650W is enough power for this rig?

    Well, looking into my tarot cards and crystal ball, I see It peaks at 400W at full load. So yeah, I think 650W may be a bit of an overkill.

  • What? 6850 x 2 = $340? Um, I could get TWO 6870's for $350~ EASY. Sure, they have mail in rebates, but who cares.


    Two 6870's would stomp the 6850's, and you would literally spend the same, if not a measly $10 more.

  • Why change the cooler from the $200 pc. It is only $5 more and still within the budget.

    Should read $2000 pc.

    Why would it be overkill? Its the kind of headroom you should have so your not straining the psu. Sure you could get away with less, but for a few dollars more than a 500w unit you can get a 650w. Its perfectly balanced and leaves room for upgrade. Its good to see what 2 6850's can do but i think if I were building this PC i would chose a faster single card and upgrade to dual cards later.

  • seller417650W is enough power for this rig?

    Yes. There is a misconception that rigs need over-sized power supplies. I have a Core i7 875k and a Radeon HD5850 running on a 400 Watt power-supply. Is it pushing it? Yes, if I clock it to 4.2 GHz and run Furmark and Prime95 none stop...
    No if I run Furmark and Prime95 at 3.33 GHz, and definitely no for any realistic workloads.
    Why did I get a 400 watt power-supply? Because it is darn silent and was recommended on Silent PC Review for "budget" power-supplies. (Bare in mind that "normal" are gold SeaSonics)

    Because he was asking if 650W was enough, when all he had to do was look at the chart and clearly see the 399W max system (CPU+GPU) load.


    So essentially, for that system, the 650W is more than enough, and ...effectively an "Overkill".

  • Most power supplies run most efficiently around 50-60% max load. That and they tend to not heat up as much at that load, so what you think is "Overkill" might be more reliable, efficient, and less likely to have failing components due to less heat.

  • Here's another question. Does it have sufficient power connectors for both cards?

    Yes
    2x 6+2 pci-e connectors
    Card uses 1x 6pin connector each

  • If you are going to overclock and spend that amount of money for the CPU, it does not make any sense to go cheap on the cooler. Next time show the difference between this cooler and the high end cooler when overclocking. It may only make sense to go cheap when not overclocking.

  • quixilver1Yes2x 6+2 pci-e connectorsCard uses 1x 6pin connector each

    I was under the impression that each requires at least 2 connectors because my toxic version requires 1x 6+2 and 1x 6

  • Most (or even all) of the charts show "March 2010 $1000 system". I was actually confused, since I always skip the preamble, and go straight to the hard numbers.

    my powercolour 6850 has 1 connector and so do most of them.
    "I have a Core i7 875k and a Radeon HD5850 running on a 400 Watt power-supply" - wouldnt try that on a diablotek 400w.

    My guess is that the $2k cooler couldn't fit in the $1K cooler case. The Nighthawk is an inch narrower and the Loki is an inch shorter. There are still a few good cases which should work with the 120 mm fan.

  • This build completely killed my video card plans. 2 x Radeon 6850 are $10 cheaper than THE CHEAPEST GTX 570. But what's the better choice!?! Damn you graphics card producers for making this so hard :)
