ATI vs Nvidia

[PinkFloyd]

The bridge between the 7600gt and 8800gtx is to keep the bandwidth rates high, if its not connected the 7600gt struggles to get the data to the 8800 fast enough and the performance as a *** drops heavily.

Interesting.....
You running a sort of ghetto SLI there?

so the person that told me the GTX needs x16 slot was wrong ?

also can you run 2 x 8 pci-e SLi in a Crossfire board?

not that 2 8800GTX cards would fit coz their to damn huge for my Asus Mobo

As I said, I read somewhere (and I can't find it for looking, if anyone knows?) that a GTX needs over 3GB/s bandwidth. Thats more than a single x8 slot and less than a x16. In SLi, even the new 650i x8+x8 boards work well with 8800GTX. I guess SLi is still using x16 bandwidth PCIe in total, but also using the bridge bandwidth between the two. So a x8 slot and a single GTX might be well choked at low resolutions with a lot of cpu traffic. There was a guy on here who moved a GTX from the lower x8 slot on an Ultra-D and his scores went up.

With only reading the title I could tell you that it's Nvidia.










I'm pretty sure the 8800GTX needs 16x PCIE slot for full functionality and 2x 16x for SLI which I think the EVGA 680i features.

The 650i with two 8x seems to do ok.

Fair enough.

Wasn't 100% sure anyway.

The thing is an ATI x1950xt is £165 (and not that much slower than a x1950xtx)

The Cheapest Nvidia 8800 is £288

So surely at the min this is the best price point and will suffice for the next year to come? Or at least until a second gen DX10 card come out or the ATI equivelent to get the true picture.
