Read The Review Here
_____________________

Today we have the XFX Nforce 790i Ultra SLI Motherboard in for review and we are pairing it with a 9800 GX2 video card, also from XFX.

Is this is the fastest hardware currently available? We aim to show you, in our 29 page indepth analysis.

Really good review, thanks.

Would have liked the Nvidia cards to have been tested on the same mobo though, i'm assuming that the 790i was used for the GX2 and the 780i for the Ultra ?
The 790i mobo is obviously faster.

However it wouldn't have affected the conclusion, 9800 GX2 looks like a fast card/s !!!

All graphics testing was performed on the 790i.

Well i have just came from reading that utter mess of a hardocp article with a mere 3 games tested and after reading DH's review, you guys are miles ahead lately of anything ive read out there.

Can't believe hardocp are using a 1333fsb 3ghz cpu either. their tests were clearly CPU limited.

absolute top job ! another top class review which showed me a lot of things I needed to know, especially when looking at some of the other reviews. that hexus article was a farce. Even disappointed with hardocps article too, although their groupies in the forums are doing some kiss assing I see.

Anyway enough of other substandard editorials. Top job from DH. ive ordered one.

Absolutely brilliant, took me a good 40 minutes to read and digest. By far the best one up again today. You guys deserve more credit tbh.

DUGG.

great looking card and the mobo is looking to be shaping up well too. Glad to see you are one of the few sites who properly patches games and uses the highest end hardware to eliminate cpu limiting. Some really big sites today have serious egg on their face due to both of these points.

With regards to the noise levels of the GX2, just how loud are they? and what about temperatures?

Fantastic review! I regret that the performance is so good because I am now tempted to go for this card. Will the 790i accept DDR2? I've got $2000 to spend on a new system (not including monitor) and want 4 gigs of ram and the DDR3 pushes my budget in a bad way (not to mention the $600 card and $360 motherboard).

Great reviews guys, looks like 2 solid products.

Have you guys ever thought to use Everest over Sandra? I dont find that sandra is very accurate when it comes to system performance, where as everest benchmarks are almost right on with what the computer is actually doing. Speaking of Memory bandwidth and such, Everest seems to be more accurate. Any thoughts on this?

not really, its a very small part of the reviews and only really included as a curiousity. im not a big fan of synthetic testing generally which is why i made the DH photoshop benchmark system. Not sure if I agree with you on everest being significantly better - I included both in the recent skulltrail review and they have strengths and weaknesses depending on the specific tests.

Interesting to see the Assassins Creed figures, nice addition, IMO.

As always, great review, the most comprehensive I've read today by far.

Unfortunately not, the 780 is DDR2.

Agreed, synthetics only are relevant to a benchmarker really, and not the average user. Still excellent work with the review, just thought I would throw that out there about Sandra

I guess i'll continue doing the beta testing when I give my old system to my son and on my work system <g>.

Any comments on this system? I don't plan to buy another GX2 to run in SLI (as I understand it is not possible with this mobo).
