Introduction and Technical Specifications



Christmas is a time for gluttony. Over indulgence. Having way more than you really should. It's also the season of giving, of unexpected gifts.

So with all this in mind we thought we'd be very giving here at OC3D and bring you something unexpected, that's also extremely indulgent. So much hardware that you will be metaphorically stuffed and promising to never eat again.

Back in September we reviewed the ASUS MARS 2. A graphics card equipped with two full GTX580 chips and costing more than a thousand pounds. Since then we've looked at the Rampage IV Extreme and the latest 2011 Intel CPU, the 3960X. Lots of high-end hardware indeed.

What if you won the lottery and suddenly found yourself flush with cash. You'd surely put the MARS 2 in a 2011 motherboard. Although if you had that kind of money, why not have two and go Quad-SLI? That would be insane performance wouldn't it?

Wonder no more. That's where we come in. Welcome to the insanity that is our festive ASUS MARS 2 SLI review. Grab a plate of nibbles and strap in.

The MARS 2 is the most powerful graphics card on the planet. So of course we've had to see what would happen if you ran two in SLI.

Some massive results from SLI, nothing is coming close to them for a while anyway.

I really enjoyed watching the video review, Nice work on putting together such a great review, it's the sort of thing you don't see terribly often someone doing a review just cause they can. Keep up the great work! Quote

I've been looking forward to reading this review since you gave us a peek at the setup.

I'm kinda disappointed and impressed at the same time. You would expect mind blowing out the box... I guess no one expects someone to spend £2k + ON GRAPHICS ALONE!!!!

Thanks for the review Tom, I can't see anyone doing the same review for quite some time lol.Quote

Get them submitted at the BOT! Quote

Great Review Mate and thanks for doing stuff like this for us we really do enjoy seeing what e-peen can do Quote

Madness indeed. Always a shame about the drivers, but the results were out of this world nonetheless.Quote

Damn, get a f'kin power consumption meter.

If you tell them you will use it in many reviews and show the brand and stuff you will get it probably free or something damn it, but thats one aspect that would easily enrich the reviews of all components.

And maybe year later you can also add measurement of noise/loudness if you feel like it. But damn power consumption is really missing and is easily fixed.Quote

I doubt anyone with the wedge to buy two MARS IIs is particularly fussed about the power draw Quote

Mr. Strawberry
there are a couple of MARS II SLI builds on the internet that i found last weekQuote

29-12-2011, 12:34:48

i love opulence!!!

i hope asus makes an ARES II with the new 7970'sQuote

Excuse me while I get that mop to wipe my drool off the floor...

Curious if that 1350W Enermax PSU you looked at earlier would have been able to handle the rig, given that it can do 1600W peak and has the power connectors to run both cards.

Regarding the driver issues with SLI, I'm no expert, but would four regular GTX580 boards offer better frame rate and stability?

Great job Tom! Really appreciate the work you put into these builds, along with the video. Will you be sending the cards back to Asus or are they letting you keep them?Quote

When possible yes dude, things is the drivers wouldnt work for toffee with both of them in.

SOOOOOOOOOOOOO thats why it wasnt done.

You need to stick around a bit more fella youve obviously missed LOADS of 98860 shout outs and folding tests in reviews.Quote
