I'm planning on making an upgrade to my aging computer soon. Now, what I'm really looking to get is a dual-core 64 bit processor like the AMD 64 X2 4600+. What I actually am asking for are opinions. Is there something I should get besides a new processor? Do you think I should go for a different processor? Right now I have an AMD 64 3200+ and I'm getting the X2 because it uses the same socket (939). I have a gig of RAM and a Geforce 6800. What are your recommendations?
