    Ok i've got a BFG 6800 Ultra 256MB at the mo, and i'm thinking about just looking for a second hand 6800 Ultra as it would be the cheapest upgrade to tide me over until I upgrade to DX10.

    Just a few questions:
    How do I know what games support SLi, is there a list or do all games released since SLi was introduced support it now?
    Do i need to get a card by the same manufacturer? (i.e BFG) or can I use any 6800 Ultra 256MB?

    FEAR and Quake 4 support SLi and i dont think it has to be the same manufacturer, not 100% though

    Ive never had any problems with any games using sli. As for mixing different cards. I think it just has to be the same Gpu and ram. Not absolutely certain though.

    I went SLi recently with 2 of the same cards.


    All games support it in one way or another, if it doesnt use the global driver or tweak your own settings.


    Its worth in that i got both cards for 90 quid on ebay, but the results are well worth it.

    Ya, read that same cards will work from different manufacturer but i think you have to clock them the same.

    The cards have to have the same Core ie Nv40/42 bit of a scam but if you can source them cheap enough its worth it.

    Ram etc doesnt matter much but getting identical cards is possibly the best idea.

    How do i check what my core is?
    Also, from reading around it seems that SLi really only shows benefits for keeping frame rates steady when the screen res is increased. I'm using a TFT which at max gets to 1280x1024, will i see much improvement in framerates if i can't use any higher resolutions?

    EDIT: Found this site which has most of the answers. Although I still would like to know how to find out which revision my core is?

    ive been using sli and some games do have issues
    fear is one of them... will not run in sli with 2x 7900gts with latest drivers
    and older games you have to switch it off
