Geezerman!!! I'm shocked you're selling it. Is that DFI board really worth it? I'd probably run another with a $50 CPU... except I already have too many older boxes. I'm waiting on the quads and another 6 months before seriously entertaining a new system.
Heck, I got boards coming out of my ears over here. I just sold my Opty 165. My MSI board is excellent, with an overclocking ability that is better than many others. My neighbor buddy just went quad, I now have his DFI Expert board to sell ( like 90 days use on it). He gave me his 3800+ X2 as a freebie, I'm trying it in the MSI board. No problems there, nice CPU.
The DFI SLI Expert is a better board than the MSI, as it should be given the very large retail price it had. It gives you more bios options, but really only needed if you want to play with various ram settings, other obscure settings that serious overclockers want to mess with. It also has a FSB that will go very high, but here again, higher than most people need. I'm not married to anything I own....well, I do have some 20 year old comfy underwear that I won't throw out....
