Star,
I wasn't trying to sound snippy so I'm sorry if it came off that way.
I just looked at the rest of 68's parts list... A64 3700... 2 sticks of memory... It's not a budget buildup by any definition of the term, so why get the older socket and single channel memory controller?
Yes, he'll have to eventually upgrade but AMD has said a few times that their dual core cpus *should* plunk into socket 939 boards with just a bios update. Time will tell, but with the release of the dual core opterons around a month away, right now seems like a silly time to put big money into a socket 754 board. Just going from an A64 3700 to a 3500 or 3200 would have saved enough cash to get a premium socket 939 board and have enough left over for a whole lot of beer.
But of course it's pretty much all opinion, so my last thought will be that every single major review site will recommend a socket 939 motherboard for gaming, because when you're putting together a gaming rig, $50 for socket 939 is a drop in the bucket compared to the price of the other parts. Socket 754 is a "value" part, just like the sempron. There's nothing *wrong* about that, but it's not the best part for the highest performance.
If 68 had dropped a sempron or A64 2800 into the rig, then maybe I could see some sense in it, but he didn't.
