Thanks a lot for the answers! Mushkin does sound a lot better, but the price is just insane. Also, my WoW guild has got some sponsorship deal with GEIL, maybe I should look in to that :>

Selectodude, ECC memory is usually even more expensive, right? I can't even find any ECC memory over 1GB and PC5300 or so in sweden.

And I'm starting to think 8GB overclockable ddr2 might be too expensive :\ I'm thinking about an alternative setup with 2x2 GB cheap PC5300 and 2x2GB Mushkin PC6400 or something so I can run 8GB with 333 FSB or 400 and beyond if I remove the PC5300 sticks. Would I get other problems if I mix different memory like that?
Should I go with one stick of each type per channel or does that not matter?
