The Motherboard i have has PCI 2.0 slots, the card im getting has PCI 3.0. What will happen if i put the card into the 2.0? (Performance Wise)

MOBO: MSI 970 GAMING
GPU: ASUS Strix GTX 970

In terms of raw single-core performance the flagship AMD FX-8350 is lagging behind intel's processor line-up by over two generations. The PassMark Single Thread scores for the i5-2500K vs the FX-8350 are 1863 to 1520 which shows that in terms of raw per-core processing the FX-8350 is lagging the two year old i5 by 23%. But no one can tell when you put 8 cores in the chip, more power and heat but we just convince ourselves Intel makes better CPU.

Same with PCIe 3.0, who needs it? With the shift of storage to PCIe based controllers from SATA, having 3.0 makes more sense when on the 97 boards we only have 16 lanes to work with. Most likely not today in what we do but they will later on.

There is no speed difference. In order for a perceived speed difference to be apparent the PCIe2.0 would have to be saturated fully. The only way a single lane in 2.0 would be saturated is possibly with something like the 690 where it's 2 cards in 1 lane, and even then there is headroom.

In other words, PCIe2.0 still is not at its data limit even with modern graphics and cards and 4k gaming, so nothing negative would happen in your situation.

Im going through the AMD motheboards and im going to be honest im not noticing any PCI 3.0 at all. Almost 70% of them have 2.0. Dont know why that it is. Then looking through Intel, almost all of them have 3.0.

that's easy :) amd does not support 3.0 yet and intel does.

you may see a few that say they have 3.0 on them but this is some kind of add-on chip that gets it's own mobo supplied 3.0 pipes and somehow accelerates the data to 3.0 speeds. how does it work you may ask? since there is no practical limitation to having 2.0 right now, no on ecan tell the difference and just convinces themselves it's better!!

That's unfortunate, i recently just upgraded my computer too. Although i probably wouldn't be able to afford an Intel. I might consider one in the coming years.
