Hi,
I'm planning to build a new Intel quad-core mid-range machine from scratch. I'm looking at either:
Q6700: 2.66Ghz, "1066Mhz" FSB (266.50Mhz really, as it's quad-pumped)
Q9550: 2.83Ghz, "1333Mhz" FSB (333.25Mhz really, as it's quad-pumped)
I'm going for a DDR2 Motherboard. The DDR2 is 1066Mhz (or 533Hmz really, as it's DDR). With the Q6700, that means the FSB and memory buses running almost synchronously (Well, 2:1 ratio so every second cycle). However, with the Q9550, I'd have to run them at a ratio of 8:5 (I think?).
I've heard running synchronously provides big benefits. Running at 2:1 is essentially synchronous. Will the benefit of a faster CPU be wiped out by the (slight?) performance hit of running at 8:5 ratio? It's a £100 more or so, so I'd like a decent jump in speed.
Anyone help greatly appreciated!
Thanks.
