6 GB of mixed-speed RAM better or worse than 4 GB of matched pair faster RAM?

I just picked up 4 GB of DDR2 800 RAM to upgrade my computer. It already has 2 GB of DDR2 533. Should I get rid of the old RAM and just use the new, or should I install all of it?

Santa was good to me this year and I received two 2 GB sticks of DDR2 800
of RAM for Christmas. My current desktop already has two 1 GB sticks of DDR2 533 RAM. My motherboard has 4 slots for RAM and I'm running Win 7 x64, so if I'm not mistaken I could actually install the new sticks in addition to the old ones and have 6 GB of RAM total.
However, I seem to remember something about how installing faster RAM in addition to slower RAM will slow all of the memory down. Will this drag on my system performance? If so, would the trade-off be worth installing all 6 gigs anyway?
