I own 2 of these AliveDual-eSATA2, 2x 939Dual-SATA2 and one 939Dual-VSTA and even the AM2Upgrade Card (and, even if it is not relevant here, the K8 Combo-Z).

I can say the eSATA2 ist by far the best and fastest board for AGP out of there. Pair it with an AMD Sempron SDX150HBK13GM (or SDX145 as the SDX150 is hard to find and expensive), the fastes (not the feature richest, this is the Celeron G470) single core processor , to avoid problems with games that themselves have problems with a dual or multicore setup. Another advantage of the board is the pci-e support and the wide range of processors available (the cpu support list on the ASRock site is not up to date). Where the ASRock 939DUAL (or VSTA) + am2upgrade board ends at the X2 6400+, the eSATA2 is just starting.

Also make sure to use the eSATA2 (ULI/nvidia M1695 and nforce chipset specific) drivers offered on the nvidia homepage, not the ones from the asrock homepage. Since i also have a large selection of graphics cards i can also say that the 6800 series does not cause any problems for me, neither agp nor pci-e (6800, GT and Ultra), at least as far as Windows XP is concerned.

Nforce 3 has too many quirks with drivers, so it's a hard pass.

Depends on what OS you use. If you use Windows XP or Linux on this motherboard, or the ASRock-AliveDual-eSATA2, then there are no such quirks, as others have already attested to.

Oh, btw Nforce 3 has freezing problems with GeForce 6800 cards.

I had no such issue on the ASRock-AliveDual-eSATA2 when paired with my BFG 6800GT OC 256MB AGP.

AMD Side:

1.ASRock AM2NF3-VSTA: I think this is the BEST AGP Motherboard. This is ONLY AGP motherboard with supporting more than 4 GB Memory. 16 GB DDR2 1066 MHz Memory Support+Phenom II X4 Quad Core CPU Support, probably it may support Phenom II X6 Hexa-Core CPU's with modded BIOS. Brilliant motherboard, I'm searching like years that. 😜
2.ASrock 939Dual-SATA2: I think, this one is the most versatile AGP Motherboard. ONLY AGP motherboard with pure x16 PCI-Express slot (Not x4 mode like ASRock 775DUAL-VSTA or ASUS P5VD1-X) . Also ONLY AGP motherboard with 3 SATA connectors (x2 SATA 1 and x1 SATA 2 connectors) . With Future CPU Slot, it can also support AM2 CPU's like AM2NF3-VSTA, Phenom II X4 CPU's and 8 GB DDR2 800 Memory.

3. ASRock ALiveDual-eSATA2 - This is the BEST! 😀 . Mine is currently running an AMD Phenom II X4 965 BE (HDZ965FBK4DGM), 8GB Corsair Dominator DDR2 1066Mhz (motherboard supports up to 16GB), 2x SATA-I, 2x SATA-II and a shared eSATA-II connector on the I/O. Paired with an Intel 160GB SATA-II SSD, an XFX 7950GT 550M AGP and a Zotac GTX 960 PCI-E. Running a triple-boot of WinXP SP3, Vista SP1 Ultimate and Debian 12. You will not find a more versatile board.

^ Very nice hardware... but oh, that XFX 7950 GT is probably going to beg you for a recap at some point in its life. In particular, the dark blue caps are the ones to beware of (usually GSC or Evercon brand.) Also, if the heatsink on that card is anything like on my XFX 6800 XT, then it's pretty much as good as junk. Even with good thermal compound, I couldn't keep the no-load temperature under 50C. Put anything 3D-load on the card, and I'd be looking in mid-70's to low 80's Celsius... which is what is -guaranteed- to kill these bumpgate -era cards with use. IIRC, the mounting holes for the cooler on my 6800 XT also weren't standard, making it nearly impossible to go with an off-the-shelf 3rd part cooler solution (and I didn't - I made my own with a spare Xbox 360 rev.2 CPU cooler.)

As for those late AsRock motherboards with AGP... they are in a similar boat when it comes to needing a recap. They often have OST-branded caps, which are pretty inconsistent in how long they last. Generally, they seem to do OK overall on Asus and AsRock boards, compared to other brands (namely Biostar.) Nevertheless, I suggest to keep an eye on those too. In the case of the above pictured ALiveDual-eSata2, it appears to use a mix of Panasonic (FL or FJS series?) caps in most of the important spots (which is good) and OST for some of the smaller caps... so might be OK to leave as-is for a while.

ASRock might be a YMMV cap wise:

-2x P4Dual-915GL - hybrid AGP/PCI-e mobo on Socket 478. First board (that I subsequently sold) had OSTs. The second one I managed to find had bulged KZGs, currently recapped with Rubycon MBZ.
