I am looking for a board to buy for my PCI 2.0 9800 GTX card. I was just curious to see if pci express is noticable slower at all compared to running this card on a PCI express 2.0 motherboard. If anyone knows i will appreciate it. This is pretty much the only thing stopping me from buying a P35 board and not an SLI board or X38.
 
I'm starting to think it will be necessary with the behemoth that is coming out next month. Just seems like if the specs are right, it might actually surpass what pci-e 1.1 can feed.
 
Necessary now? Prolly not. In June, still prolly not. One or two years from now, prolly so. I remember the hubub over agp 2x then 4x then 8x then pci-e 16x. At the time they were released there was no real performance benefit. A year later we start seeing 2 or 3 more fps with the next higher interface speed. A couple of years after release we start to see the gap widen considerably. If you already have a pci-e 1.0/1.1 board I doubt you will be missing any performance for a while yet.

That said, I don't think it will be like the whole eide133 to sata change. Where otherwise identical hard drives still perform today nearly the same in most cases on either interface. We will see a benefit to pci-e 2.0, just not right away imho.
 
tomshardware.com did a write up you should look for, actual benchmarks taken with the different speeds. if i recall the difference was not that large. i do know however, that it is already necessary to run two 9800gx2 cards in sli. so for future sli rigs, i wouldn't be surprised if 2.0 was necessary very shortly.

SLI is a very different story from single card, though.
 
PCIe 2.0 also supplies more power. Can the power connector just crank out more juice if the card is in PCIe 1.1? I wish someone would do a review of a high end card in 2.0 and 1.1 to see if there is a difference. I would rather not buy a new mobo for June's cards.

i'm telling you tomshardware DID run a comparison of high end cards running in the different PCIe slots. I'm just too lazy to go search out the link for you. It wasn't that long ago though.
