Intel Core i7 Review Thread

[Bellisimo]

It does but not nearly as much as you are alluding to ... 500 MHz over 400 Mhz FSB is not going make up 60% performance delta.... what you are seeing in the guru3D data is pure CPU power over CPU power.

offcourse it will not make up the 60% perf delta, i didnt say that
i said if you would overclock the fsb to 500 and keep the frequency at 3.2 ghz for the qx9770 you would see a similar gain (not as large)
also dont forget intel cores communicate with eachother (2 dualcore dies on a quadcore) through the FSB
so FSB is occupied with this:
- Intercore traffic
- Memory acces
- Peripheral stuff
- Graphics stuff

a 1600Mhz fsb will not cut it....
especially when there are 3 very powerfull graphic cards in the system

thats why i stated the QPI bus is largely responsible for the huge gain with 3-way SLI

Do you have a C2Q?? It is an easy experiment to do ... you won't affect your gaming benches by much more than 5 or 6%.

i don't, i have a E8400, but i don't have 3*GTX280 so i wouldnt be able to test it

oblivion is screwed, but look at QW with only 2 gpu's
