well, yes.  But, there's a catch.  To get the 790, you have to invest in real expensive ddr3 ram.  so yes, the performance is better, but this is defintely performance you'll be paying for.

Yea its about a 300 buck difference in my build, with just the 790i and the upgraded memory.
 
Im iffy on if its worth it or not. Going from a 780i to a 790i and from 2GB of 1066 to 2GB of 1333. Then again the 1333 would match the bus speed of the E8400 i want. (damn the demand on that thing jacked the price up on it vs the Q6600 almost equal to it now doh!!)

The number 1333 is actually the MT/s or also known as the effective speed. The E8400 actually has a bus of 333mhz which performs 4 transfers per cycle (known as quad-pumped). (333mhz * 4 = 1333)

The processor speed is determined by the bus speed and a multiplier. The E8400 has a multiplier of 9. E8400 3ghz = 333mhz * 9

DDR ram is duo pumped so the advertised speeds of ram is actually the effective speed.

ATM, DDR3 ram is uber overkill for anyone not overclocking to the extreme limits.

yea im still a newb at that stuff, i can never get the math right. In any case, since im probably not gonna go watercooling i probably wont want to consider that extra 300 buck investment sounds like =P. I suppose I dont have the money for super hardcore, and will just have to settle for hardcore lol.

ive only got what you see in my specs, and im running COD4 at its highest settings silky smooth. Which is weird, because Oblivion at its highest twitches pretty bad at times. But ive got HDR enabled and it only twitches in highly lit urban areas.

Im sure that the 780i and those gts's are more than plenty.

If you get the 780i EVGA board you can d/l the 790i motherboard driver for it and PRESTO instant 790i  but only the 1066 dominators will work ddr2------But all other features are there.  
First run of 3DMark 06  score on 780i drivers 15233 DS shipped base drivers  went to evga got the 790i ultra drivers And presto 16055 instant upgrade for free   ohh and ran it again today with new nvidia beta 174.74 64bit drivers 17387 is mt new score

I just want to repeat the warning about flashing a BIOS.

Particularly one not intended for a specific motherboard. If it goes poorly, you can brick the motherboard. Presto- $250 paper weight. I'm glad it worked out for Sharariebrum, but before anyone else gets the bright idea to do likewise, understand a bad flash of the wrong BIOS version is well outside of DSO's warranty responsibilities. Make sure you are both financially, and emotionally prepared for things to go "poorly" before you even consider doing this.

Only reason I did it is because I modder I personaly know has done it and looked at the driver from the EVGA  In a few weeks the 780i driver update will be this same driver with a few forceware tweaks to fit the FSB of the 780i board.
 
I need to post a link here soon of another guy that added this same info at Newegg.com I beleive it is in the customer reviews of the EVGA 780i board.
http://www.newegg.com/Product/ProductReview.aspx?Item=N82E16813188024&SortField=0&SummaryType=0&Pagesize=10&SelectedRating=-1&PurchaseMark=&VideoOnlyMark=False&Page=7  (second review down Pros: nvidia finally fixed the sata bsod problem so now this is a very dependable board install the 790i drivers from evga and your problems are solved they will be releaseing a new file for the 780i board it will be the same as the 790i drivers listed under the 780i board

Cons: they shouldnt have release this until all the bugs had been worked out

Other Thoughts: better late that never i guess )
 
Good place for insta fixes---I had one problem with windows not using all 4 gigs on second boot up.  Did the remove 2 sticks and then restart, then put the 2 back in.  And I dont have raid but the sata/raid drivers from the 790i are the same I d/l both and looked at the drivers they are the same.
 
I know not to flash the BIOS with the Bios part of the driver that would screw NB preatty good hehe.  But the feature sets for the driver the sata and nforceware internet drivers crap of the driver set is what you need.  Not the MAIN BIOS flash.  If you read that as FLASHING your Bios to the 790i your right anyone who I hope has at least a 10% brain would know not to do that.  So I guess I will be clear the FEATURES of the driver the Nvidia forceware drivers sata drivers and other FEATURES of the driver are what you want DO NOT EVER FLASH THE 790i BIOS to the 780i.

Yes, I read that as a flash. Probably too much work, not enough sleep before reviewing your post Sharariebrum. My apologies.

There have been other BIOS hacks used on the previous series of boards (which I will not get into), so my "radar is up" when it comes to this sort of thing.

Drivers are another matter entirely. Worst case, you have to re-install an OS.

Ive actually compared the price difference from the options ive chose. Originally i planned to get a 780i with 2GB of 1066 ram. I checked over the 950si machine and did the exact same options except with the 790i and 2GB of 1333, the price difference was only 50 bucks.
 
Worth it for only 50 bucks more? I know tomshardware did a ram review that proved that ram speed really isnt all that important as the performance increases are amazingly minor...but the 790i mobo should be a decent improvement over the 780i...but is it worth 50 bucks ?

Assuming it is a $2500 machine, $50 is 2%.  Are you getting more than 2% return on your money?  If the price is higher than $2500 the cost/benefit analysis gets easier.
 
It is the same math I would do if I was getting dual video cards and SLIing them.  I did that math when I went with 2x160GB HDD & 1 500 GB HDD for my dual boot set up  over the 1 250 GB and 1 500 GB.
If you're in a fair fight, you didn't plan it properly.

yea thats an intresting take..and it hovers around 2600-2650 so yea. Its extremely close performance wise at least from what i took from that toms hardware review, where they showed that faster ram really has very little effect on the speeds.
 
Really though, going from 1066 to 1333 is not a huge leap anyways, im more intrested in the performance packages given in the 790 vs the 780

Should I be worried about this? Especially considering i plan to have the E8400 overclocked? Im thinking i may just stick with a 780 now cause im scared of this major problem...
 
Nvidia Admits Problems with nForce 790i SLI Chipset

by Anton Shilov

[ 04/17/2008 | 10:35 AM ]

Nvidia Corp., a leading designer of graphics processors and chipsets, recently admitted that its most-recent chipset for Intel Corp.’s microprocessors may cause data corruption in case processor bus and system memory are overclocked. Earlier customers blamed previous-generation Nvidia’s core-logic sets for data corruption under the same circumstances.

Apparently, when computer enthusiasts overclock processor system bus (PSB) and memory clock-speeds on systems that are based on Nvidia nForce 790i-series core-logic, they may experience data corruption on hard disk drives. Earlier end-users complained about the same issue on systems powered by previous-generations Nvidia nForce chipsets.

“Nvidia has received reports of data corruption when using certain high speed memory and overclocking the front side bus. Our engineers are currently investigating this issue and as soon as we have more information, we will provide an update to this knowledge base article,” a statement by Nvidia in its technical support forums reads.

Even though this is not the first time when customers complain about data corruption, neither Nvidia nor any of the mainboard makers have disclosed the reasons of the problem.

That would include "previous-generations Nvidia nForce chipsets" like the 680i, and 780i, in addition to the latest 790i. I have yet to experience any sort of problems, and my FSB and memory are most definitely overclocked.

This is something I would keep an eye on, but I wouldn't get too alarmed, at least not yet.

Alright, i just got a little worried because i was on an overclockers site and they had a poll, and for EVGA boards it was 33 people not having corruption problems to 27 with corruption problems....which seemed pretty high, but you never know with online polls whether people were being honest or not.

You have some time yet Sunfighter. Keep on the lookout for a BIOS update for the 790i. It's new. It's bleeding edge tech. There are bound to be a few bumps in the road. At least it's not frying RAM like the 680i did at release.
