pci-e 2.0 compared pci-e

post #1 of 12
Thread Starter 
is there a real difference, can the cards and boards out now use the extra bandwith.

I am thinking about sli's by getting another GTS g92. i am going to have to purchase a new board tho.
what series should i get, 680 sli 750sli or 780sli. i am thinking the only series that offers 2.0 support is the 780sli, correct me if i am wrong. but is it worth it for the extra money.

also i want something that is going to overclock at least as well as my current board DS3R

rep for good answers or advice for these questions.

For Nvidia Chipsets you need a 750i upwards for PCI-E 2.0, it's not worth it mate. You will not see a difference as no card on the market can max out PCI-E let alone PCI-E 2.0

Not sure which supports pcie2.0, just check their specs. I know my 780i does for sure though that my 680i did not.
The cards are backwards compatible and currently you wont really find a difference in performance if any. Pcie2 its more of a future expansion I believe.
I just came from a 680i from Asus, and Id say if youre spending the extra money based solely on pcie2.0 then it isnt worth it. Spend it on another small hard drive or treat yourself to a nice dinner.
All of the nvidia chipsets (newer) oc pretty well. I got my p5n-t deluxe and the first day it hit 1600fsb rock solid without a problem.

What range are you trying to achieve in terms of FSB?

PCI-e 2.0 won't be needed for a very long time, so spending money just for it is stupid. By the time it becomes mainstream, it'll be time for a new board anyway

PCIE- 2.0 is useful just not needed for your gpus its a bus system and not just graphics use it. So It has to be more bandwith then you use , since each user scales their system to what they need , you may have 6 hd's where as I have 1 , you may have qaud sli and I have just one card. The whole point is it needs to be able to scale to what is needed. The other side of this is that like has been stated , gpus do not use
that kind of bandwith , so for performance increase it will not work , but for overall
funtionality it will far surpass the pci bus lane for example.

right now my board is at 1500 on a Q6600, it was at 1800 tho with my 6550 i had prior to upgrading, i am pretty sure my overclocking abilitiy is being hindered by my CPU i have a pretty high VID and only a tuniq for cooling. i have not intentions in water cooling, okay think i am going on the edge of Too much info. so just wanting to stick with the same overclocking performance.

so it seems like the answer to the 2.0 question is, do not purchase using that as a factor.

what are the differneces between the 680 750 and 780 series of boards then?

okay one last question in regards to this thread, and thanks for the help so far....

is there going to be big performance differce between using 2x8 pcie 2.0 or 2x16 pcie 2.0

i do not plan on upgrading for a while after this, so i want to make it worth it, but i also do not want to spend extra money if i do not feel i need it.

in regards to this question could you give examples of what the performance diffence would be

No, it would be unnoticable. Maybe on cards like 9800GX2's and GTX 280's it would slightly come into play but for your setup no. You won't notice a thing and performance would be the same regardless.
