[QUOTE=Dee;2478666]Regarding P55 and PCIe, that isn’t strictly true [B]RJL65[/B]. All PCIe x1 sockets are connected and use the PCH and don’t steal lanes from the two main PCIe x16 sockets.
Sound cards, tuners etc etc, only ever use PCIe x1 in my experience, so unless the user wanted Crossfire or SLI, then yes, each card would only run at x8. But then again, PCIe x16 on P55 is onboard the CPU package itself, and much more efficient and has much lower latency than the arrangement on the X58 chipset. Not to mention it uses much less power. The i5 is also a cool running chip as it has no HT, and overclocks very well.
In the benchmarks that i have seen, the i5 750 is faster than the i7 920.[/QUOTE]
Thanks for the correction. What I have seen until I re-read this was based on inaccurate comments in other forums. The P55 itself does have eight PCIe lanes, but the graphics PCIe x16 lanes are on the LGA1156 CPU die itself. This gives a P55-based i5 or i7 system a total of 24 PCIe lanes. That’s plenty of available lanes to handle a single high-end graphics card plus a PCIe TV tuner card and a high-end PCIe sound card (if you ever need one for audio production rather than mere audio listening). That still leaves six available PCIe lanes (or one PCIe x4 plus two PCIe x1 slots), if the motherboard manufacturer chooses to implement them all, open in a typical P55/LGA1156 system.
