Socket 939 moderkort, 3 att välja mellan

Im currently looking for a new motherboard for my socket 939 "AMD64 4400+ 2.2Ghz & 2Mb cache", 1024Mbx2 Corsair CMX-4000PT 500Mhz, 2 x Point Of View 7800GT, Creative X-Fi Extreme Musik.

So my first choise in a LINEUP of 3 mobos is:

ABIT AN8-32X,nForce4 SLI X16,Socket-939

together with the "ABIT Guru Panel"

My questions to this are, how mutch can i increas voltage and can i se the current voltage ? (On the motherboard im using no i can only increas +0.1 & +0.2 without seeing the current voltage). The same question goes for the CPU voltage settings.
Does it have a fully [16x, 16x] support in SLI mode. I know it only perform 1-3% better then [8x, 8x] in best cases.
Is there any known issues with the X-Fi cards or is it fixed with the newest BIOS ? Is there any specific ABIT comunity(forum), moded BIOS and sutch.

My seccond choise is:
DFI Lanparty nF4 SLI-DR

The only thing im worried about here is that there are reports about issues with Creative soundcard products. Im not sure if they aply to the X-Fi series ? Other questions are the same as for the ABIT board.

My third choise is:
Asus A8N32-SLI Deluxe, nForce4

The same questions as for the ABIT & DFI board's.
I dont know about any issues at all, are there any ?

I hope u guys respect this.

Anledningen till att allt står på engelska så beror det på att jag ställt samma frågor i ett engelsk språkigt forum o inte orkar skriva om allt igen.
Den andra anledningen är att jag inte fick så många svar som jag hoppas på o frågar därför här oxå.

Tackar för svaren.
Det lutar mot ett DFI som jag eventuellt kan köpa loss för en tusing.
