Richard M, For a quick an easy score boost try the beta cat 4.10 drivers, they give around a 20% boost in 3rd score. Oddly my cpu score is unstable and was also affected by the driver update, on my first bench it got 4200 somthing with a large boost to the first cpu test, ever since i havent been able to get close to it, even with pushing the cpu harder and stuff. though second cpu test has gone up so the score is about equal there.
Interesting to see someone has got an alledged ti4200 to go through the bench and kick out simply a stunning score, me thinks its hacked though.
Have a look for yourselves
