There's absolutely no difference or very little difference between 8x and 16x today as the cards don't use nowhere near the bandwidth available...

as for the cards....if you have the money go with the 7900 series as it's the latest....

but 6 months down the road?

 

Go for the 7900 series. The 7900 GT's are priced ~$300, the GTX ~$500. The 7800's are about the same.

I don't know...no one can predict if they are ever going to bottleneck the 8x Spec...but if you're that worried, by all means get the ASUS....

They say with that with that ASUS A8N32-SLI there isn't really much of a performance increase with full x16 bandwidth.

7800 110nm manufacturing process

7900 90nm manufacturing process

 

7900 generates less heat because of the manufacturing process therefore, has higher clock speeds....also the memory they're matching the 7900 clocks higher than than the ones matched with the 7800....

VIVO is video in/video out

If you need video input and video out then go for the one with VIVO. Are you ever going to connect any vcr or dvd player etc.. to your computer? Are you going to output to a tv?
