pcie 2.0 video card on pcie 1.1 slot

I don't think different versions would bottleneck that much that you could notice.. What are your system specs and what resolution are you willing to play it?

Bandwidth information:

Capacity per lane (each direction): 16 lane slot (each direction):

• v1.x: 4 GB/s (40 GT/s) << my GTS 450 scores 25 GT/s
• v2.x: 8 GB/s (80 GT/s)
• v3.0: 16 GB/s (128 GT/s)

So there would be bottlenecking only with a much more powerful card... but not with this guy :)

Also make sure that your psu has a 6 pin (or 4+2 pin special) power connector for the card.

You would get the same performance with pcie 1.0 and 2.0 slots in this case.

I strongly recommend you to add some more memory (ram) to the system, is it ddr2 or ddr3 ram? Are you planning to upgrade any other parts of the PC, or you just want a card and nothing else? :)

I haven't read the whole guide, but it seems pretty handy for beginners.

Also check out some youtube videos. These videos are coming from a reliable guy as well





Good luck with the whole machine! Open a thread in the chillout section when you will get to the point of ram question or overclocking please :)

Cheers

Yes, the short of it is that PCI 1.1 is equal to PCI 2.0 running at x8.


Thing is, most single modern GPUs still do not saturate a 2.0 lane yet, not even a GTX 580.

From the tests Ive seen, the only cards that start showing a performance hit at x8, are the Dual GPUs on a single card.

So running that card on a PCI 1.1 should not hurt anything at all.

The worst case scenario, you might loose 1-2 FPS, but I doubt it would even be noticeable.
