Stuttering Match Engine Problem

I keep getting a Stuttering match engine and i cannot understand why. It works fine sometimes but then it starts to stutter. Makes no difference if its on high or low. Surprising considering the power of my computer

3.2ghz Dual Core

2 gig DDR 2 800Mhz

2 x 2900xt's in crossfire using 8.10 drivers

I've had the same problems. The match engine seems to have a love affair with the 8th and 53rd minute in my game sometimes when it will hang on that particualr minute for some time.

I have had some luck in speeding up the general day to day processing and match itself by deleting as much stuff of of my desktop as possible and emptying the recycle bin. This is a bit of an old school solution but it appears to have helped a little for me.
