Input on Crossfire & SLi

post #1 of 5
Thread Starter 
Is it the games fault for not taking advantage of both cards. Like in most games when you add a second card you only get 10% more for example. I know motherboards and the PCI-E bus speed can make it slow down but reviews showed that 8x PCI-E is just as fast has 16x & PCI-E 16x 1.0 is just little slower than PCI-E 2.0. -- I always wonder if it's really worth it to get another card to get Crossfire or SLi if most games don't support it and my frames only increase by 1.2x.

What's your input on this? Please share experiences, reviews or anything you like

Either way your going to run into some driver bugs. Overall it's the drivers that make the engine run and you can't trust ATI with that. nVidia drivers will go better. SLI all the way. You get crossfire you gonna run into problems..gl,

it's not worth it. After paying a premium on a 800w+ PSU, a SLI or CF mobo, 2 video cards, you spend so much, it's just not worth the minimal gain.
When people say add another card later, you can buy a single video card, and it will perform better than 2 older cards!
If you do go CF or SLI, do it when you buy the system, or not at all

I just xfired a pair of 4830s. I already had a board and psu that would handle it, so no other upgrades. My 4830s run very comparable to a 4870 1GB card at about $50.00 cheaper.
