Thanks for all the comments and advices. To inform all, I bought these already,
MoBo: MSI 865PE Neo2-V
RAM: (2x) Kingston DDR 256MB 400MHZ PC3200 CL3
CPU: Pentium 4 2.8 GHz SL6QB 533/512
Sound: Creative Audigy ZS 2
So, still couldn't decide for a GPU. I of course don't want it to be "the best" of all or don't want it to run all the games in a decade perfectly well. The deal is, I don't want an XP machine. The deal here is that I only want to use W98 and play mostly early XP games and some DOS and W98 games, if possible. It doesn't have to run all DOS games, neither W98 and XP for sure and I won't get sad when/if I won't be able to run some games, it's okay. But for me better compability and/or performance for early XP games more important than playing DOS games but would like play them if I can, sure. Long story short, want to play mostly early XP games on W98, as best as possible with the possibility to play some DOS and W98 games, as much as possible. Overall, I'm not sure if I should buy FX 5500 or Radeon 9600 for this purpose, or don't know if I have any other option left, please guide me through. Also, please let me know if I'm going good enough with my hardware choices as for now, if there's anything I should do to improve my system. Lastly, I found Samsung SyncMaster 797MB and SyncMaster 793DF, any idea which one to buy or any other ideas for CRT monitors? Thanks in advance again!
