Mb it not pci express 2.0, how much worse would a pcie2 card be on it?

[SkeeterUK]

I have a asus p5kc motherboard and seems that its not pci express 2.0.

Just buying atm a asus 460 which is pci2.0 card.

What if any performance will i be missing?

Edit - Hmm seems my gtx 260 was pciE 2.0 as well, wonder how much performance i was losing out on.

Hi,

In my opinion barely anything, for example a GPU does not use the 16 lanes on PCI express 2, let alone 8 lanes. Basically a 460, will not even bat an eyelid in your PCI express 1 slot.

I know because I moved from type 1 pci-e slots to type 2 slots with an Nvidia 8800 GTS. You 460 will not strain that bus on the motherboard, even if it only uses 8 lanes.

Cheers

Von

Well i just tried my GTX580 in my second slot on my Asus Maximus IV Gene-Z and in the top one it got P6771 and in the x8 socket it got P6554

Yes but thts a 580, not a 460 (460s are not monster cards like the 580 series)...and the difference seems (is) minimal.

I ran a GTX 275 in a 16 lane (pcie 2 board) with the other in a four lane, did not notice any major issues at all.

A x16 PCI-E 1.0 slot is the equivalent of a x8 PCI-E 2.0 slot.

At most you're losing out on a few percent.

Consider this test and look at the x8 result which is what you have the equivalent of.

Cool ta for that. So not really noticeable.

Only in benchmarks.
