fumoboy007 You've seriously done a world of good for my osx installation and I cant thank you enough.

It does seem to be the Unsynchronized TSC for cpu 1 and I checked the voodoo TSCSyn out. I got lost completely when you said compile the sources. Is there anyay you can direct me in the right direction of getting it done? Because I installed a kext I found on here but it seems to be for core2. But it did fix all the lag issues. Yet the Unsynchronized TSC for cpu 1 still shows. So its obviously the wrong cpu info in the plist. So yup any help regarding that would be highly appreciated. Thanks again.

Update : I ran some geekbench tests the results are below.

Update 1 : Without Voodoo TSCSync + No multiprocessing geekbench score = 1964 (No Lag)
Update 2 : Without Voodoo TSCSync + Multiprocessing geekbench score = 7844 (Lags)
Update 3 : With Voodoo TSCSync (core2) + Multiprocessing geekbench score = 3485 ( No lag)
