You are right, my first tweak is to use a pentium M on air, which needs a 3,1 a64 to be beaten on air or a good X2 cpu like 2,8 or a bit more.
That's a pretty expensive "tweak" . I can't afford to replace either my processor or my motherboard unfortunately .



I just broke 5K with my entire system stock. Only the card overclocked, to 688/1323.

That's 2.2 GHz of Athlon64 POWAH for you .
