You know, nobody's forcing anybody to upgrade. If you want to, do it. If you don't, then don't. I want to upgrade, I'm not sure where, so I sit and read reviews from everywhere I can, weigh the results from what I know about the sites, laugh at Kyle from [H], and then come here to sort it out by comparing peple who have had it for a lot longer's scores. (Yes, I know that's improper English.)
Based on my research, there's no GOOD choice right now. You have Conroe, fast, with buggy boards and RAID issues, AM2, which is a lot like my 939, except I have to buy new RAM and a new board, for very similar performance, or I can stay 939 on an EOL'ed socket. I'm waiting for a real reason to even repair my system.
We can argue all day till we're blue in the face, but at the end of the day, none of the options look all that inviting. Conroe will not make a real difference in anything but my compiling, and if I compile my kernel to take advantage of it a simple 3800 X2 can run rings around it. (the joys of Linux, total scaleability.) The issue is then not what does everyone need to do but what do YOU need to do. None of us get up in the morning and use our PCs for the exact same thing, so why say the exact same setup every time for everyone? Doesn't make sense to me...
Oh well, I'll probably get flamed for this, but it's just my opinion, and I don't really care if no one shares it. Being a Linux user, I bet I look at things differently anyway...
