BF2S Forums Is it possible to run SLi with two different make cards?

Save up for a better card,no point of SLI that crap.

Just look at the faq on www.slizone.com.
Got your question cut/paste below:

Can I mix and match graphics cards?
In order to provide optimal symmetric scaling, SLI technology requires the NVIDIA GPUs to match. For example, a GeForce 7800 GTX must be paired with another GeForce 7800 GTX. Likewise, a GeForce 6600 GT must be paired with another GeForce 6600 GT. However, using the latest Release 80 or later graphics drivers, NVIDIA GPUs sold by different manufacturers can be used together in an SLI configuration. For example, a GeForce 7800 GT from vendor ABC can be matched with a GeForce 7800 GT from vendor XYZ.

Can I mix and match graphics cards is one of them is overclocked by the manufacturer?
Yes. A GeForce 7800 GTX that is overclocked (for example BFG GeForce 7800 GTX OC) can be mixed with a standard clocked GeForce 7800 GTX.

Can I mix and match graphics cards with different sizes of memory?
While it is not recommended, NVIDIA does offer this flexibility using Coolbits. When purchasing a second graphics card, you should try to match the memory size so that you are ensured full value and performance from your purchase. For example, if your first card is a GeForce 6600 GT with 128MB of memory, you should purchase a second GeForce 6600 GT with 128MB of memory. However, using Coolbits (value set to 18), you can force both of the cards to use the lower of the two memory sizes and operate together in SLI mode. When dissimilar memory sizes are enabled to work together using Coolbits, the effective memory size for each card becomes the smaller of the two memory sizes. Instructions to enable this feature can be found here.

Do other graphics card features such as VIVO need to match?
No, you only need to match the NVIDIA GPUs (for example GeForce 7800 GTX) for SLI technology to work. As mentioned above, NVIDIA also recommend that customers match the memory size to ensure that they get full performance and value out of their graphics card purchase.

Well, I think I'll stay un-SLi'd then.

Now, what kind of northbridge motherboard should I get? Preferrably a good clocker and <100€ on www.multitronic.fi .

GIGABYTE GA-P35-DS3 - € 91,05

Will that card clock better than an nForce 650i?

Should do. It'll certainly run far more stable.

Ok. Thanks

SLi is really only good for super high resolutions. Non-SLi can actually outperform SLi at "normal" resolutions in some cases, or at least be really close.
