Ok this is gonna sound like an idiot question but i do not fully understand PCI express.

So my brother and I were talking about it and he said that one no matter how much i try not to i am going to have to go PCI E. Now this is a problem for me cause i have no freakin clue how the Video cards in PCI E slots work. He was saying something like to get the full affect of the card you have to buy two and bridge them.. WHy the hell would anyone wanna do that? And do you really have to do that? I donno it just doesnt make any sence to me..If you wouldent mind could you guys try to explain to me how it works?
 
PCIe has double the bandwidth of AGP. Well, ifg you're using one card, it's running at 16x, while AGP (Accelerated Graphics Port) is running at 8x. The advantage of PCIe is more memory bandwidth and the ability of connecting two video cards to add up lot more performance. I'm still not an expert on PCIe.
 
It doesn't really matter for current cards (6800 series and x800 series) whether they're pcie or agp speedwise. The new 7800 GTX... just came out only on PCIe... don't know about agp releases. PCIe just has more possibilities than agp... whether or not we're seeing those currently is another issue. As far as two cards with a bridge. That's nvidia's SLI. If you buy a special SLI mobo which has 2 pci-e slots, you can stick in 2 nvidia cards (certain 6 series and 7800 gtx cards only), then the work load is split between the two cards. ATI's dual card solution is called "crossfire" which will come out some time soon... i think. To have upgradability and future proofing, pci-e is the way to go.
