Re: New Vidcard or MOBO?
If you are talking about jittering on NFS:MW , then maybe thats normal .. i get some even with 2GB of RAM. most likely its a game issue , but again 1GB RAM is much better than 512MB. & 2GB will ensure the smoothest experiance possible for all games today.
as for the 6800XT , i'd say get it if its in your budget!! theres no such thing called "overkill" for video cards.
