i have 7800gtx 256mb single card how much better is a 7900 512mb sli ? my friend is giving me the 7900s and mother bord for free . but is it worth the hastle to redo my machine for sli? will i gain that much if any in my gamming?
I'd say you'd get about 50% performance boost for the upgrade and if he's giving you the cards for free then yes it's definitely worth the upgrade and time it'll take you. Really it's just a a matter of swapping because the drivers are the same. It shouldn't take you more than 15-20 minutes. Just checked the VGA charts and it looks like a considerable gain. Go for it.
YES! Don't be so lazy. That will boost your performace and will last you much longer and then you won't have to upgrade from DX9 for some time but IMO the 7800 GTX doesn't have much time left until it's left with nothing much more than medium settings.
will i have to reformat my drives since im changing the mother board ?
