Couple things to consider here.

1. In a system like that Dell, there will be absolutely no benefit to getting PC2-8500 over PC2-6400. Stick with the PC2-6400 is what I would do.

2. That Dell may not even support PC2-8500 RAM so definitely look into that first. Dell motherboards are on the lower-end and proprietary so basically they're junk that usually supports the minimum...

3. How many RAM slots total do you have in that Dell? If you have only two RAM slots than you will only be able to fit the two new RAM sticks you buy. If there are 4 you will be able to mix & match the 8500 (if the motherboard supports 8500) with the 6400 but it could cause issues and if it works it will scale down to the 6400 speeds anyway...

My recommendation is to buy 4GB (2 x 2GB) of the PC2-6400 DDR2-800 RAM and just use that alone, sell the 2 x 1GB kit you have.

Also, remember, if you're using a 32-bit OS, you'll only be able to utilize just over 3.5 GB or something like that so anything over 4GB would be overkill anyway.
