i dont know what this guy is talking about

i have this board with a core 2 duo e8600 and was able to overclock it to 4.18Ghz and the bios made it fairly easy to do so

i was also able to overclock my 2 GTX 260s and 8gb of ram

this board is extremely stable and i have had no problems with stress tests
i can run crisis warhead at 1920 by 1200 on max setting @ 35 to 42 FPs so i give this five stars for simply being perfect

I have built many PC's over the years and had more trouble with this motherboard(I even got a replacement from the reseller so tried two) then any other component. If you check out the newsgroups , which I should have done before my purchase, you will find many users with problems like mine of hanging and crashing behaviour at intervals of 30 minutes at most, from day one of using this motherbaord.

These mostly detail issues with the default Bios settings which apparently include inadequate voltage and memory settings, some users managed to make things a little more stable with alterations to these.

I myself tried such as updating the Bios from the XFX site, updating the drivers , which incidentally seemed to makes things even worse, and don't even try running any of the inclusive Nvidia performance/utilty tools provided because the crash this will undoubtedly produce may require a windows reinstall to even reboot.

I also tried the usual removing and changing of all other parts within the PC,memory, sound card, graphics card etc everything pointed at the motherboard. Another point is this board 'boasts" it can support 2000mhz memory sticks, however its designed to clock the memory in Bios at 1333, its expected a user should manually update this setting to there applicable memory setting, I actually bought my memory with these increased settings in mind. Well I wouldn't bother even trying that people because you will not even see your desktop on reboot, its totally hopeless.

So I found myself in the situation with a "ninja" PC that crashed or hung when running such "intensive" games as the speadsheet induced Football Manager, lets not even go there with something like Bioshock.

Solid, stable, top-of-the-line 14 Aug 2008
By J. Elkins - Published on
Verified Purchase
I built a system with this motherboard, an Intel Q9450 CPU, and 4MB of OCZ memory. Booted up fine, Windows Vista installed with no additional drivers as long as you don't use RAID (though I did put the latest chipset drivers on when Windows finished installing.)

Now that it's up and running with Windows updates applied & software loaded, it's as stable as any system I've ever used. Forget what you've heard about problems on previous nVidia motherboards - this one works and works well. I avoided building my own system for years because I thought it would be a hassle getting everything to work together, but I've had no such problems. (I did have problems with system crashes after waking from sleep mode, until I installed the P07 BIOS and the latest nVidia drivers. Now there seem to be no sleep-related problems.) And of course, it is insanely fast. Haven't had the chance to try SLI yet... maybe in the future.

As you would expect for this price, the monitoring and overclocking utilities are excellent. If anything, the BIOS has TOO MANY options. Tons of ports, including older ones like PS/2 mouse & keyboard, IDE, floppy, and 1394. Even a serial port is provided (though not on the back plane.) Six SATA ports. Ten USB ports (six on the backplane, four on the motherboard.) Two eSATA ports (one in the rear and one on the motherboard.) Two gigabit ethernet ports. Only an on-board 56K modem is missing (that is not a major omission, but it's handy for faxing every once in awhile.)

My only complaint is with the slots provided. There are three PCI Express X16 slots, but only two PCI Express X1 slots. The board also has two legacy PCI slots. This board could have gone without one (or both) of the old slots, and provided more PCI Express X1's instead. It would seem that anyone who would spend $350 on a motherboard is going to upgrade their legacy PCI cards too. So, if you do tri-SLI with double width video cards, understand that you will have only one PCI Express x16 remaining. If you do dual SLI, you'll have a legacy PCI and a PCI Express x1 left over. So, if you want a sound card and a TV tuner card on top of that (and who wouldn't?) you may run out of space.

Less significant, there is a small fan provided to cool the chipset, and it blows hot air point-blank onto the side of the card in the top PCI Express X1 slot. I wish they would have oriented the fan to blow in a more benign direction.

In summary, this motherboard is not cheap, but it's terrifically fast, customizable, and expandable. If you're not on a budget, consider this for your next system.

Best deal on a tri sli 790 board 20 July 2010
By dreamlines - Published on
Verified Purchase
My Asus striker extreme motherboard was in for repair and I didnt want to wait for it be be reurned so what does a hardcore computer user do? Simple.... buy another sli motherboard for the meantime. I looked at the egva verson of this motherboard back when it was new (and $300 retail) and it was very tempting.... now a few years later I find this great deal on a referb one.

I was a little worried from the reviews but in desprite need of a tri sli 775 motherboard I figured why not. When I got the board it was not open box, dent box or even looking or labeled referbished. Its possible I got lucky but this looks 100% new to me.

The motherboard runs GREAT! I had ZERO issues hooking it up and it runs awesome. The box contained more coards than I will ever need and my perfered <hard plastic> sli board.

This is a GREAT board for anyone looking for a dual or quad <775> motherboard. DONT THINK.... JUST BUY IT.... A++++ DEAL.

Buy the EVGA Version of this Board NOT the XFXForce Version 4 July 2008
By clicker - Published on
The XFXForce products and their support policies STINK! We had flashed the board with a new BIOS only to find out that the this company posted incorrect files to their web site.
I shipped the board back to them via overnight express, I told Dan, and countless others that this is a production system that have this board, and that I have now been without a working board for 8 days. (Again, thanks to their INCORRECT postings on their internet page, for both BIOS AND MOB Drivers (x64 intel drivers where actually AMD Drivers!)
They ended up having to replace the board b/c of defective workmanship (Not the BIOS) and they shipped it back GROUND adding another 5 days, after verbally stating they would ship it back the way they received it!!! What is amazing is that I had contacted the EVGA folks who responded within the hour via email, and immediately diagnosed the situation as a "wrong bios".
