I am led to beleieve that upgrading my 2000 XP to a AMD 2600 XP will make a big difference to Frame rates because of the huge increase in FSB speed from 233 (is the correct FSB speed for a AMD 2000XP?) to 533 Mhz.Is this correct, or am I being misled again.Best Wishes,and Many thanks,ChrisEGBB

I assume you are going to get a new MOBO, since your present MOBO probably doesn't support that FSB or CPU speed. What about your graphics card? What speed is it going to render the graphics?

I just did the 2100+ to the 2600+ upgrade. Your FSB was 133x2=266mhz, AND WILL BE 166X2=333MHZ FRONT SIDE BUS. Don't know where you got that 533 figure from. I saw a nice increase..but not a woah..look at this son of a gun cook now!!!! Increase of 1000+,- in 3dmark 2001SE. I am pleased with the upgrade over all.My system....ABIT mobo kx7-333 @ manual 166mhz @>13 mutiplier and latest bios upgrade in soft menue. 1 gig pc2700 ram@166mhzx2= 333mhz.Unless your board can do it (multiply ram to less than 166mhz x2), you will not be able to run this processor @ 166mhz x 2=333mhz , unless you have pc2700, or greater ddr ram. See my previous post on upgrade in this forum.

A faster FSB but not that much faster.The 533 number you have is from a Pentium 4 FSB which is quad pumped 133.33X 4=533. David

Hi David et al,Many thanks for your help. i HAVE DECIDED TO STICK WITH MY AMD xp 2100 FOR THE MOMENT, until there is a significant increase in Bus Speeds. It sounds like we are all being duped here!, as the system is obviously restricted by the speed of the FSB.Best Wishes to all,Chris EGBB
