    I think you can CS different cards, and if not have one as dedicated PhysX card(whatever that is :) )

    EDIT: oh do you mean trade it in?

    Yeah I'm gonna trade it for a 6950 sorry if that wasn't clear :)

    About CFing with different cards, its possible, but then the system would be limited to the clock rates and memory amount of the weaker card, so not worth keeping the 5850 and adding a 6950.... besides the Radeon can handle PhyX, I installed it to play Metro 2033 and there are no issues, works like a charm :)

    I actually thought to do CFX with the 5850s but that means I will have to upgrade my PSU because 525W with a CPU on 1.35-1.4 Vcore + CFX won't cut it I think... so I'm better off with a single 6950 unlocked to 6970 with my current setup :)

    Sounds about right as far as CrossfireX with your current psu.
    When overclocked to 910 - 920MHz with my GTX460, some graphics demo benchmarks draw up to about 350 watts (total system). With a second video card attached, the system power load could go up another 225+ watts.

    Newegg has a one day special on the Seasonic X-750 for $119.99 with free shipping when you use a special Newegg subscriber promo code. This offer expires tonight (Wednesday) at 11:59 PM (2011-05-11). Their "regular" current price is $159.99 plus $5.99 shipping and the newer X-760 currently sells for $183.99 plus $11.30 shipping.

    The X-650 is currently still available at the regular price + shipping.

    That's a great price, however, living in Israel is not so simple :) Anything over 50 USD shipped into the country will be taxed by customs by another 40% , which means that a 120 USD PSU will eventually cost around 170 USD, and that's even higher than the retail price here I think...

    EDIT

    Surprise surprise, I just checked, even after customs its still almost 300 NIS (90 USD) cheaper :eyes:

    Like I said, everything is really expensive here, the retail of the X-750 is almost 240 USD :(

    But considering the fact that I'm going to plunk another 100USD for the card + 150 that I already spent on my 5850 + 90 USD I spent on the Zalman, I'm gonna hold off the PSU upgrade for now and settle with my 525W...

    I missed your previous post #80.
    Most better made power supplies can temporarily sustain 110 - 125% of their rated power, but only for brief periods of time. Efficiency will drop off a bit, but they will still be in spec with voltage and ripple (electrical noise) regulation. The general recommendation seems to be that your psu should not be run above 80% of its rated power for extended periods.

    [H]ardOCP is one of the best psu review sites, and their extended eight hour torture test is run at 80% of rated power. For me, HardOCP, JonnyGuru, PCPER, and HardwareSecrets are the best psu review sites and their overall findings and ratings are very similar.

    I'm a Seasonic fan and you can buy some excellent Seasonic made power supplies from Antec, Corsair, and XFX. XFX is currently 100% made by Seasonic, and most companies sell power supplies made by two or more different suppliers. The XFX models and Antec TP-xxx "TruePower New" models, are Seasonic made power supplies that offer excellent performance that is often significantly less expensive than the Seasonic branded units. Naturally you'll get most of the quality features, but the efficiency might be somewhat lower and psu fan noise won't be up to Seasonic's level. My Antec TP-750 is based on the Seasonic MD12 series and I bought it during the end of year holiday sales 18 months ago for $70 after MIR. Most of the Corsair models are top notch, including the models that aren't made by Seasonic.

    I'm willing to bet your life that the quote you posted is from HardwareSecrets.

    **edit**
    My Newegg/Seasonic post was for the benefit of USA customers that might want to jump on today's deal.
    I'm well aware that prices in Europe, Australia, and most other countries are considerably higher than prices on this side of the pond. That's why I listed the less expensive Seasonic made models.

    Well Jim, what more can I say, I am impressed...

    That quote was indeed from the Modu82+ review by HardwareSecrets, I'm no match for the Guru :notworthy: :)

    My opinion is (And that's for every aspect in life) if you buy something, buy the original, I have been eying the Seasonic PSUs for a long time now and they are definitely produced extremely well, plus I love their modular models, so I think my next PSU will be a Seasonic one, but I assume that this will be in a year from now, after the warranty of the Enermax expires.

    Thanks, but don't be impressed, I've read so many psu reviews from the sites I mentioned that I often recognize psu quotes that I see elsewhere.
    It's pretty clear from my animated gif in my signature that I'm a firm believer in quality power supplies. We all have to make comprises in our hardware selection, but to me it's just plain dumb to cut corners when it comes to power supplies. How many of us would build a quality house on a crappy foundation?

    I cringe when I read power supply reviews where they can't produce their claimed power or their voltage/ripple/efficiency results are only borderline passing. I don't even want to talk about the cheapy garbage that catches fire or produces fireworks during testing.

    Temps at 65C full 100% load on a Quad core CPU with 3200MB test, that's what I call a good cooling performance

    It's not fully stable yet, need to run Prime95 overnight to make sure the RAM is stable.

    Jim, Chike, thoughts on how to move on? :)

    How do temps compare to what they were before? Did you use the thermal paste that came with the cooler?
    How much vcore in CPU-Z?
    How to move on? Like the song say, the only way is up.

    I just finished running Prime95 blend test overnight, ran for 8 hours and no issues, so looks like this is stable!

    I did use the Thermal paste that came with the cooler... previously I was using MX-2 but tbh I don't really think that there is a difference between the two...

    About the temps, IBT peaked at 65C and with the previous OCZ Vendetta 2 my peak was 69C so that's 4C like you said, in Prime95, the maximum was 54C compared to 60C with the Vendetta, it's weird, guru3d reported that their i5 peaked 46C when using P95 on the Fan's 100% setting, I expected to peak at 50 tops... maybe the Q9XXX just runs hotter than the i5/i7?, but it's still a good cooler, plus my room is located on the top floor where the ambient temperature is a bit hotter so there's a difference between my room and their testing environment.

    Vcore in CPU-Z as shown in the screenshot is between 1.34-1.36 with LLC enabled.

    Gonna try 3.8 tonight again, will need Vcore 1.4 I assume and probably a notch up in VTT... I discovered that my CPU can't reach high clocks with VTT below 1.3...
