Pros: Looks nice, pretty colors. Open box had everything that the retail one did for only $136. It was a steal for a 780i board.

Cons: No audio connection for your DVD or CD rom drive. How are you suppose to listen to a CD or DVD that's played through your DVD or CDdrives?? What is a JSPD01 connection??

Overall Review: Install your memory before your huge graphics card or else you won't be able to push down the clips

Pros: Worked for 3 months, SLI

Cons: Worked for 3 months so I had to RMA the board. I sent it in and got it back with half of the heatsink missing and the board looked pretty mangled. I called MSI and they said they would send me a shipping label. I never heard back from them. I called back a few weeks later and sat on hold for an hour. That happened a couple of more times. When I finally got ahold of someone they hung up on me. I called back again and someone said that they would send out a heatsink. I have yet to even see that. I also sent a couple of emails that they never read, apparently. Now I have a $250 paperweight sitting at my house. The lack of bios updates is also a good sign as to the way that they run a buisness. Also this board never clocked very well, my ram neverran at its rated specs and I never got proper bandwith results. This is all hardware that is running great on another board.

Overall Review: MSI has the worst customer service that I have ever delt with. I will never buy another MSI product again. Avoid MSI like the Plague!

Updated review 1/19/2009 6:24:06 PM

Pros: Well I thought all the issues were resolved until I swapped to an E8500 for testing with a GTX 260 and OCZ reaper 8500. The video distortion in crysis warhead was unresolvable and went away immediately after putting a Q6700 cpu into it. I do not recommend this for anything over 3 ghz. So for someone wanting to use it for a Q6600 or a E8400 okay but that once you attempt to overcolck forget it. The nvidia chipset can't perform as well as the 750i board from the same company. I have 2 of those in my kids gaming systems for 6 months with no issues.

Cons: Video distortion and too many flashes needed to load Vista for the average person. The BSOD issues were with nvgts.sys and memory timing which is easy to fix. The FSB going to 1333 should not exceed 3ghz you have been warned.

Overall Review: The sound card and software were very and since I didn't buy it for it for that it was a nice suprise. The sli layout is nice as well. Using this for my son with a Q6700 and 8800Gt and he enjoys it for the game she plays. I play crysis and for that the upgrade path is either a phenom II or I7.

OC Board for experts 1/17/2009 9:29:58 AM

Pros: This is a great board once you work around nvidia 780i issues. I recommend it for experienced technicians since it requires flashing the bios to ver 1.2. You can only do that in XP due to the sata nvgts.sys driver in vista causing bsod. Once flashed and the driver updated either by newest nvidia or MS updates it rocks. Otherwise you will have to use a floppy to flash and that is not for the faint of heart. I have no complaints since resolution was obtainable due to my 20 years experience.

Cons: Board bsod problem took quite a bit of time to resolve but well worth it. I hope my info helps any out there. I believe this to be an Nvidia 780i chipset related issue rather than MSI. Once DDR3 comes down this board will quickly be obsolete along with 775 cpus.

Overall Review: Bang for the buck this board really kicks it a nickel with Woldale E8400, 8500 & 8600 series. With a GTX 260 and no OC I reached 13,500 3d mark. I will be experimenting with OCZ reaper 1066 2gb ram sticks 4 each for my testing a write a 2nd review.

Would not detect Keyboard 11/27/2008 5:06:29 PM

Pros: Good caps and overclocking potrntial, but I didn't get that far.

Cons: Shipped with bios rev 1.0. Per MSI tech support, this bios does support newer 45nm cpus. With my E8500, it would get to the "Press tab to post or del to enter bios setup" screen but would not detect keyboard. Tried ps2 and USB keyboards with no luck. After researching, I found several other people that had this problem. Looks like newer bios revs solved this problem, however no keyboard support makes for flashing bios a bit difficult. Huge props to Newegg's customer service in helping me out getting a new mobo. Opted for EVGA....

Overall Review: Had several other MSI boards with great success.

Great Board so far 9 months 11/10/2008 9:44:54 AM

Pros: Intel Yorkfield Core 2 Quad Q6600/2.40 GHz, Zelmon CNPS9700 Led 110mm 2 Ball CPU Cooler, 4 G Crucial Balistic Tracer DDR2 1066 Ram. CPU running 3.07 GHz 1371 FSB (342 x 9) + .1250 V moved V-Core to 1.304/1.312 Ram @ 1077 2.1V 5-5-5-15-2T
SLI Ready- set to Expert, NB Voltage 1.325, SB Voltage 1,525 This is an update to my last OC attempt. I didn't raise the voltage enough on the first try. Really stable with no issues.

Cons: Can't sean to get the SATA wotking as I would like - found Nivida drivers that helped - running 2 WD 320's and WD500 along with 2 Lite-On Burners off stata ports
as IDE's. Really works great! It might be me so I not holding the SATA issue against the motherboard.

Overall Review: CPU started right up as 2.39 GHz and RAM as 800
I'm new to OC-ing so it took me a while to get the manual part figured out. Had it running 3.3 GHZ yesterday but backed down to 3.07 GHZ because I didn't want to push it. I like the lights on the MSI board and the Crucial Ram and Zelman fan - Look great in the clear Gigibite full tower clear side case.
