Which MOBO for E6300: Gigabyte DQ6 or Asus P5N32-E SLI?

Hey THG readers,

These are the components:

Mobo: GIGABYTE "6 Quad" iP965 or ASUS P5N32-E SLI
Mem: 1x Transcend® JetRam™ High-Performance 1GB DDR2-800 240-Pin Module, i think its 5-5-5-12 and max voltage of 1.9V, typical of 1.8V (another one a bit later to make it 2GB) (Kingstons are too expensive and Corsairs only come in matched pairs...)
CPU: Core2duo e6300
CPU cooler: zalman CNPS9700LED
GFX: 1x Asus Geforce 7600GT Silent pci-express
HDD: 1x Seagate SATAI 300GB drive, 1x Seagate SATAII 320GB drive
FANs: 1x 80mm (side), 2x 120mm (front, rear)
DVD: LiteOn dual layer writer
CASE: standard p4 tower with reasonable ventilation
PSU: Enermax Noisetaker 600w

Upgrade Path: core2duo path up to the quad core, and then the gfx from the 7600gt to an 8-series card.

1) Which mobo would suite it best?

Ive read reviews on the gigabyte, but the asus is brand spanking new.

And ive heard that you must update the bios on the DQ6 to make it compatible with nvidia gfx cards.

Where I stay the DQ6 is a little bit cheaper than the asus board.

2) What is e-sata used for because the DQ6 has them but not the asus?

I hope this wasnt too confusing, thanks for your time
