I just ordered a Mac Pro with the stock 2gb of memory. I want to order 4 more GB. Should I order two sticks of 2gb, or 4 stocks of 1GB (more $). Which is better and why?

Either way will be fine, but the 2GB sticks would give you additional room for growth down the road if you want more than 8GB
 
So there is no slow down at all with going with 2 x 2gb sticks vs 4 x 1gb sticks?

I'm ordering the same system with the stock 2GB. Will 2GB be sufficient to run Photoshop for the first couple of months? (I'm asking because there doesn't seem to be anywhere in the UK to buy the memory from yet).
 
According to this 4 sticks is faster.

I don't know why. Maybe it is because there are more physical tracks from the memory to the CPU, allowing more data to flow.

Quad channel with 4 sticks, versus dual with 2 sticks.

However, in either case -- if the memory is adequate -- then it really doesn't matter which choice you make. Since either option is a lot faster than virtual memory and a slow and sluggish 50-100MB/s with a HD.
