sandra usually acts like a retard.
u want to know diff of 1t and 2t, try 3dmarking

btw, did u get bios with cpc enabled?
coz if those disabled one, even if u set cpc on, your performance would be as equivelant to 2t.

correct me if im wrong. been long time since ive touched axp's.

anyway the best bios i ever used was the mantaray d26's with cpc enabled.
those really rocked!!!!!

yeap try and see
with cpc enable and cpc disable
how ever i suggest using 3dmark 01 to see the difference as 3dmark 03 depends more on vga capabilities.

or u can try using super pi test to see the difference..either super pi or prime 95 benchmark test will show you the difference
