Ah ok, my cpu is the X2 4400+, so that's a Toledo I see. So the speed will be at 400mhz with 4 dimms, but the timing 2T. How much of an effect does that have? (more on that further down the post)
I read articles
here and
article here which were great reads. The first is someone who picked mostly the same parts as I'm getting, and he mentions how (and links to a review on this site) Command Rate between 1T and 2T is in reality on a few % difference in performance.
So I think I'll go for the 2 x 1gb sticks, then at a later date add another 2.

In the second article linked there, it's about understanding what memory timings mean, also a good (if a bit too technical for myself) read. For the first four numbers at least, comparing a 512mb stick with a 1gb stick, the speeds are:
2-2-2-5 - OCZ Gold VX PC-4000 512mb
2-3-2-5 - OCZ 2GB (2 x 1GB) 184-Pin DDR SDRAM Dual Channel Platinum
It's the second timing that's different, and about the second number, "the performance impact of this setting is often neglible, as memory tries to store data from programs in sequential order. It tries to keep the same row for a single program, and ordered columns to reduce the time for tRCD." So there doesn't seem to be a lot of difference, but then I'm missing the last two numbers of the timing.
I also made a note that if you run a bus side speed of 500mhz instead of 400, you get a 25% increase in speed there. I wonder if that's something easily done on the DFI Lanparty... I guess so since it's reffered to as an overclockers dream so often? Or at the very least my "Toledo" X2 4400+ CPU should keep it at 400mhz instead of dropping to 333mhz if I understand correctly.
(phew, complex, haha!)
