Within a couple of months I plan to get Vista. Mainly to enjoy dx10 in games and especially now since I've read that with the release of SP1 Vista is much more stable. But: will I need to throw away my sound card or will it still somewhat work under Vista? Also, I guess that although my processor is the crappiest c2d... at 3.0Ghz it shouldn't be that bad and should still be somewhat future-proof, however to add more ram I would need a 64bit OS and there wouldn't be much point to purchase another XP now... I've read a lot about 32bit vs 64bit - mostly they outline the advantages since 64bit is the way to go for the future, but are there any disadvantages of 64bit OS? Final question I've got 4 ram slots with 2x1GB in dual channel. Would dual channel still work if I purchase another 2x2GB and add them?
