    Hey, sorry about the Opteron thread, I don't know how to delete it. I decided that my XP mobo and processor are holding me back. First the Nforce 2 RAID controller SUCKS, second the XP series is a giant leap behind Athlon 64. So 754 is the perfect affordable and upgradable transition to next-gen. I've got an AGP 6800GT so I'm not willing to give that up for a full PCIe upgrade.

    So my question is, I see 3200+ mobiles and 3000+ (Clawhammer and Newcastle) core 754's, and both sockets say they're the same specs (like both 3200+'s or 3000+'s have the same clock and cache). I just don't know if 754's have on-die cache's like 939's. So if they do, are they the exact same performance? Like a 3000+ Newcastle 754 is the same as a 3000+ Newcastle 939? Thanks

    By the way, is the Clawhammer a better core than Newcastle for overclocking? And how about the mobiles, are they better overclockers like the old XP-M's? If you could give me a recommondation for one to get I'd be very thankful. If you don't want to check sites, then how about a recommondation between these:

    3200+ Mobile Clawhammer (DTR?)
    3400+ Mobile Clawhammer
    3000+ Newcastle
    3700+ Clawhammer (desktop)
    3700+ Mobile Clawhammer

    Cheaper is better for me (unless the mobile 3700+ is waaay better than the desktop processor, it's not in my price range).
    The 3700+ desktop I'm looking at because it comes with a free motherboard (one that I was looking at), but it's a Biostar and I hear they're not too high-performance

    939 has support for dual channel memory, 754 doesn't, thats the big one. ClawHammer is basically a bigger level 2 cache over the NewCastle. Both come in a 754 and 939 pckage, but the 754 awlays have a 200MHz speed increase over the 939 version. EG: 754 3200+ is 2.2GHz, while a 939 3200+ is 2GHz. I'm not that sure about an advantage that a mobile Athlon has over a destop version, besides maybe a lower TDP.

    Okay thanks dude. Well okay, do 939 Opteron's have hypertransport technology? I would assume but I don't know. I'm looking at the 144, the legendary price/power processor. Just found out that 939's have AGP support, and some even have AGP AND PCIe support. But if anyone has heard of the AGP/PCIe boards, can you tell me if they're worth it? AND ARE OPTERON'S COMPATIBLE WITH ALL 939 BOARDS?

    Do you mean a board that has both a AGP and a PCI-E 16x slots on it? Then what Don suggested, there is not much choice in that area. The 939 Opterons should work with all 939 boards, but I can't be a 100% certain on that (all new boards should, and I haven't seen any incompatibility yet). And they do have HTT.

    Okay awesome. Thanks again guys. Now it's just between these 2 boards:
    http://www.newegg.com/Product/Produ...N82E1681312323,N82E16813123222&SubCategory=22

    I'm a hardcore (well as hardcore as air-cooling can get) overclocker, so between the 2 boards, which is a better overclocker? I know the MSI is great, because MSI makes good motherboards. But I haven't heard of Epox and it's more expensive, and the reviewers claim to get really good overclocks out of them. Thanks

    UPDATE: I just checked a website, the Opteron 144 is very well overclocking with the MSI board, but there seem to be bugs in it. Like the fact that stock it's not compatible with double-sided DDR for dual channel. I hear there's a tweak to make it work but still.

    yikes. Dude, thank you, SERIOUSLY, for all the help. That's the exact kind of board I'm looking for, but it's 3 times as expensive as the ones I'm looking at. If both the Epox and the MSI end up sucking, I might have to go for the DFI. But thanks a helluvalot dude, I had no idea DFI made a good AGP/939 board.

    I just picked it, the MSI because there's a new update built-in to the mobo that makes it support dual-channel double-sided DDR400. Thanks again for all your help everyone, especially djbben.
