Intel OC Question: 266 FSB vs 200FSB

[AWPC]

CPU is the 670J 3.8Ghz 2Mb L2 Cache. Standard FSB=200.

Question is I am about to upgrade my system next week when the X1900XTX & or 7800GTX512 arrive. I already have an Asus P5WD2Premium mobo & 2GB DDR2 5300 Ram ready to go. Just waiting to drop the Gfx card in.

My Options are:

1: Do I run this CPU @ FSB200 x 19= 3.8Ghz (default speed). Ram would only be operating @ 200 instead of 266.

2: Mild CPU underclock to FSB266 x 14= 3.724Ghz (mobo allows CPU lock downwards to either 14,15,16,17 multiplier) so Ram would be running @ default 266x4=1066.

3: Slight overclock FSB266 x 19= 5.054Ghz (mobo will handle it and my Thermalright XP90C is a very good cooler so should be no probs there either).

My main concerns are:

A: Will the increased FSB speed compensate for running the CPU @ a lower multiplier.

B: Does having a higher FSB help/hinder the CPU in keeping up with a high end GFX card.

TIA

A slight overclock is 5ghz?

Try both an benchmark, its the only way to be sure.

Sorry should have said mild FSB overclock (200>266). However 5Ghz is believe it or not nowhere near what this exact same CPU & stepping can achieve. 7.2Ghz is the tops with exotic cooling 5-5.5Ghz on air 6Ghz+ with water.

The spec in my sig is my current hardware. I have a new PCI-E + DDR2 system to build but waiting for OCUK to get the gfx card in mon/tues next week.

5-5.5Ghz on air with my Thermalright XP90C is possible as I have seen many others do it. Phase is only really if I wanna go for the 6-7Ghz+.

As for the FSB I will try 1066 first then benchmark to see if that is better than a higher multplier. When I have determined that presume my next step will be to increase volts until the rig is stable.
