Ok, you can call me ignorant, but I don't know much about PCI express. I plan on building a computer with an AMD processor and I am thinking about getting the LANPARTY UT nF4 Ultra-D motherboard. Now, in the description it says "dual Xpress graphics supported". I'm assuming that means it uses a PCI express video card. But the dual part? Does that mean that it needs two video cards or it can use one or two? And if I just use one, will the performance be crap?
 
It can use 1 or 2 in SLI mode. If you opt for 2, they need to be nvidia cards that are SLI compatible. As for performance it depends on the single card you buy. 2 6600GT are as good or better than 1 6800GT. However, you could by 1 6800GT now and then get a second one down the road. 2 6800GT's will perform better in most cases than a single 6800 Ultra. Either way, don't skimp on the power supply. At this point any ATI pcie card will not be able to run in SLI on a nForce4 SLI mobo and I don't see that changing any time soon. Good luck.

Actually with the Ultra board GoldBug specified you can't do SLI unless you are lucky enough to get on of the boards that can be modded to SLI. With a non-SLI board you can use two graphics cards that will run seprately from each other and can support up to 4 monitors. You can, as most people with the Ultra boards do, use one graphics card.
 
Ah, my mistake. So its a Dual Head pcie 16x mobo. Weird, I would stay away from that board unless you need to build a work station, plus how does it have enough lanes to run both cards in 16x.
 
It doesn't, waht it does is use each card seperately for different monitors. Think like using an AGP card and then a PCI card. The differece is that the PCI videocard, doesn't suck in this idea. It arranges the pipelines as to how the cards are configure, I believe.

Actually, the Ultra boards are a very good solution for those not looking at SLI. It is a cheaper alternative to SLI boards and still has the same features and performance as the SLI chipsets minus the SLI part. In short, if you are not going to build an SLI system then the Ultra based boards are the boards you should get.

Why stay away from it? It is a great board.
SLI only runs at 8x (unless we are talking high end operton boards) and is more than enough as we aren't pushing the threshold with today's cards.
