MoBo for 3x 1600p monitors?

post #1 of 4
Thread Starter 
Buddy just ordered his 3rd Dell 30" 1600p monitor for his gaming setup. Here is his current setup

2700k
580
Intel Mobo
8gb
2tb storage
128gb SSD boot

I don't see a reason to replace the CPU, so I think we will stay on the 1155 socket. We knew he needed to upgrade his GPU in order to handle this kind of output so I convinced him to go with 680s over a single 690 because he will actually be able to use the 4gb of vRam unlike most people (2x EVGA 680s w/ 4gb). Now we need to find a replacement mobo since I want to make sure he is able to max out the cards and wont get throttled down by the lanes. I am opting for a board with at least 16x/16x PCI3 lanes, because again he is actually in a position to use these lanes to their fullest unlike the rest of us. Any suggestions as to which board? Price really isn't a problem, and I quoted him around $300 since that is what my Sniper board cost and it comes with a 16x/16x/8x/8x setup, so don't be afraid to throw out some higher end boards. Or am I going about this all wrong and you have a better game plan?

Also, I know we can use the 580 as a dedicated physx card correct? Never have SLI'd before so this is new to me, but I have done a fair amount of research in the past.

this was my board, and unless I can find one I like more, I may just say pull the trigger on this one.

4GB 680s will not be able to game well at that resolution, they just don't have the necessary memory bandwidth. The only cards you should be using are the 7950 or 7970.

As for a motherboard nothing too extreme is needed. A MSI Z77 MPower would be fine because it has three 16x slots, take note though that CPU does NOT support PCIe 3.0 so the cards will still be running at PCIe 2.0 speeds.

EDIT: Which Intel board does he have? If it's the Intel BOXDZ77GA70K or Intel BOXDZ77RE75K then they are both fine.

ahh totally forgot that the 2700 was 2nd gen and doesn't do 3.0, damn. hmm may have to look into that retail edge deal then and grab the 3770K while its still cheap. And I thought the 7970 only had 3gb bandwidth, wouldn't the 680s be better then?

Memory size and bandwidth are different. The 7970 and 7950 both have 384 bit memory buses while the 680 only has a 256 bit bus. This means that at higher resolutions the 680 simply can't keep up with the amount of data transfer necessary for a smooth gaming experience. Over 1920x1200 resolution the 79xx graphics cards really start to shine over the 6xx series.
