Re: What's Better? (PCI-E question)
I saw a review where they put a 5970 and a GTX 295 in x8 slots, and they each lost about 20%.
As far as what it takes to saturate an x8 slot, a 5850 is where it will start to hurt performance, with it becoming more noticeable with higher clocks. Anything more powerful loses more.
I have done a lot of googleing on this.
