Asus p5v800 vs Asrock 775 dual 880

Which of these 2 mobos is recommended? The Asrock has 4 PCI slots and
the Asus has 2. But the Asus supports SATA 3 Gb/s where the Asrock is

1.5.

Any thoughts/suggestions? I just bought a new AGP video card so I do
not want to buy a PCI Express card, and I still want to use my ATA 133
(IDE) HD and these boards support both AGP and PCI Express (for when I
upgrade). I have been pricing barebones systems with these 2 mobos
with an Intel 820 CPU (along with heat sink and case fans...but no
other hardware at this time). Memory I'll buy on Ebay, and
slickdeals.net to find a SATA hard drive when I need one.


What web sites do you prefer for buying a barebones system? I do not
feel comfortable putting a system together myself, and don't know how
much I'd save anyway. I am comfortable installing hardware, though.

I understand the Asrock supports dual channel memory, yet the Asus
pci-e slot runs at 16x where the Asrock runs at 4x.

Since I will someday upgrade to pci-e and use my machine for games,
which is better...the memory or the pci-e slot?

Thanks, Paul...I think I'll wait and put together my own system using
my current hardware. So I want the least expensive mobo with a true
PCI Express x16 slot. Which do you recommend? Do all newer mobo's with
SATA also support IDE? Since I don't have the money for a whole new
system I wanted to buy a cheap PCI-E video card and use my current HD
and optical drives for the time being.

Thanks!!
