I do this so the CPU does not affect the overall power consumption figures and we can see a clearer picture of which GPU requires the most power.

I have also been thinking of adding a "worst case" scenario consumption test much like I did in the PSU reviews. Bacially running the Batch Size Test on the GPU while running OCCT in the background on the CPU. This would give a clearer indication of the power consumption in a GPU-intensive game that uses the CPU for physics calculations.

A good example of this would be in Crysis Warhead where I have routinely seen power consumption above 575W from the wall using the EVGA GTX 260 Core 216 Superclocked card.



They will be back but I am presently building the new PSU and GPU test system which will center around an X58 / i7 combo. The first PSU tested on it should be a little surprise from Corsair.


I'd definately want a good 750W if there was a possibility for that kind of draw... I get nervous whenever real power draw gets over 60 - 70% for extended periods of time.

Well, 575W from the wall equals about 460W draw from the PSU itself based off of an approximate 80% efficiency with the HX1000.

I'm running a Q6600 at 3.8 GHz and a EVGA GTX 260 core 216 with the shaders overclocked to 1512 MHz, all on a Corsair VX550W without problems (and folding hard on both the cpu and gpu sides).

Yes, yes, I think that's a very good idea.

HX450 maybe?
My, oh my...I'm eager to see that review.

Good job mate. Looks like this thing may be worth the few extra $ over a 4870. Not to mention it would fold it into the ground.

I'm thinking about picking one of these up.

I wanted to do SLI with the BFG GTX-280 H2OC (love the single-slot card!)

BUT

If they're bringing out a 55nm core revision, it might be worth waiting on.

Of course, I could get the cards now and do tradeup, but I don't think they're changing the model.

Ah...decisions.

Glad you managed to get the review out which I enjoyed and lookign forward to the psu reviews again

This looks like a really nice card and a great deal from BFG with the warranty and trade-up. I'd hate to see them go out of business so this could help them out a bit.

You must have a pretty brutal Crysis benching system to get those averages though. One thing is that the price is on par with a 4870 1gb which if overclocked might give this card a run for its money when the aa is turned up.

Not ONE of the manufacturers is able to send us a 1GB HD 4870 card...which is too bad.

And yes, my Crysis benchmark is VERY tough.

And amazingly enough, those scores highly resemble the numbers I see when I, you know, actually PLAY the game. Who would have thought it?

Nice review, although now that you mention it, any particular reasoning behind revamping your PSU test setup? You had a setup at one point that could kick a 1kW PSU's butt. Has that been taken down?

Makes you wonder don't it? Anyways, it is a 10 minute timedemo.

Revamping was needed since the test system was no longer representational of a system an enthusiast would be running.
