Need Help with low FPS issues while playing WoW

[SBoeks14]

At times while playing WoW I am getting on average 60fps then at other times my frames are running around 15fps and can drop as low as 1-2fps. I just bought a new graphics card and this did not solve my issue can anyone help?

I am running:

AMD Sempron 3300+(64bit)
Windows XP Media Center
2gb DDR PC3200
Sapphire ATI x1600pro 256mb 8xagp
Driver is the newest ATI driver from OmegaDrivers

I think this should perfrom well can anyone see any reason from this that my FPS run so low at most times in the game.

Thanks for the help

What psu are you using and what wattage is it?

It depends on where it happens in WoW, if you are entering a large city (Iron Forge) then FPS may drop because your computer has to render those 500+ people in the city. However, if it just does it at random times when you are out fighting somewhere deserted then you may have a problem.

Thanks for the replies guys,

I am not sure what PSU is in there I can check that when I get home and let you know. As for the times it does it, it is mainly when I am in major cities when people are around or during raids or when I am in groups.
