yes, all that is Ok.
and remember to go to you advanced display settings and check and see if there is any "Clock Frequency" option avalible... because there shouldnt be unless someone enabled overclocking for your Vid Card.
if your video card has 256mb's of physical ram on the card, then you could set your Video AGP apature size in bios to 128 if you wont, but it prolly will not make a difference between 64 or 128
