RELENG_6 VS RELENG_7 @ AMD64

Hello there

Could you please tell me if migration to FreeBSD 7 would give my machine
better hardware support? Today I'm using 6.2 and really got a headache from
problems, hardware compatibility mostly.My machine is:

Asus M2N-SLI Deluxe nForce 570 SLI
(no driver for mcp55 integrated lan, I'm using nfe driver port from OpenBSD,
and almost not working driver for Nvidia Media Shield RAID which I'm using
in MIRROR mode)
1024MB ECC DDR2 800Mhz
2 x WD Caviar RE 250 GB 16MB cache SATA-II
(no NCQ support in ATA driver)
Athlon 64 X2 4000+ AM2
(poor SMP)

This machine is working as router/server and today it's a piece of unstable
*** ;). I know that RELENG_7 is -CURRENT and could be unstable too, but I
would appreciate your opinion if upgrade to 7 is worth in my case.
