SLI-Same Gpus,diffrent memory?

[Nevakonaza]

Is it true that you cannot SLI a graphics card with the same GPUs but diffrent memory size on the cards?

For example...

Card 1 - GTX 460 768Mb
Card 2 - GTX 460 1GB

I was planning to SLI,but cannot fit another regular GTX 460 in my case due to where Gigabyte put the second Pci-e slot on my mobo,the only way id be able to SLI is if i had a really thin cooler GTX 460 like the up comming KFA2 GTX 460 which uses a slim cooler...

although i asked them and they dont currently have plans for a 768mb version...

arghh

What case and motherboard do you currently have?

My Mobo is - Gigabyte GA-P55-US3L

my case -Coolermaster CM690

Another card wont fit because the top of my power supply is in the way,you will get what i mean from lookin at my mobo pic

Unfortunately, that motherboard doesn't support SLI (crossfire only) and the second main PCIE slot only runs at x4 speed.

Oh man i did not know that,well thats that plan out the window then

Well, given the circumstances it seems like the only reasonable upgrade path for you is to sell your 460 and buy some more powerful card like hd 6950 or gtx 560

I did actually consider getting a 6950 and unlocking it to 6970,but at £250 ish its a bit expensive :/

Im gonna wait to see how much the GTX 560 is.
