PCi-E 4x VS. 16x : What's the big deal?

post #1 of 2
Thread Starter 
I'm playing CS:S right now through the 4x port on this DS3P board, simply because the 16x port is blocked by the Zalman NB cooler and I have full settings @ 70FPS

1680x1050

Uhm. What's the difference supposed to be?

As this article shows the difference is only noticeable for 8 series cards, even for X1950XTX the loss in performance is minor.

Therefore a 7900GS won't loose much in performance. But if the card is struggling with performance then a 16x slot may give it the boost required a game playable.
