n00b question about SLI boards...

post #1 of 10
Thread Starter 
...can I buy an SLI board but only use ONE graphics card? Also, somewhat unrelated - can DX10 ready cards play games that are made for DX9 (for example, Medieval II: Total War or STALKER or perhaps even really old games like GTA: Vice City and San Andreas)?

Thanks.

Ok on the subject can you use 2 NV cards on a crossfire board or 2 ATI cards on an SLi board?? Or do they have to be the relative make??

You can mod the BIOS to run SLI on some CF boards (the 975X I believe) and you can also run CF on some SLI mobos, but I think modding the BIOS is a plain old bad idea. Besides, dual card solutions are all lame-o e-penis stroking anyway.

SLI (two nvidia cards) can only run "officially' on an nvidia chipset that supports sli... You can run 2 ATI cards, but cross fire wont work because you need an ATI chipset on the motherboard for it to work...

now, there is a work around to get SLI to work on intel chipsets... just google it...

short answer,

SLI only works with nvidia cards and a nvidia chipset on the motherboard...

Crossfire only works with ATI cards and a ATI chipset on the motherboard...
good enough

Except you can run CF, true CF, on the Intel 975X chipset, as well.

Not necessarily, some people like to run their games at pretty high resolutions.
