Hi, i'm having problems choosing a motherboard for my first build (I'm probably going about this backwards by choosing mobo last but oh well).
Current component selection:
 
CPU: E8400 Core 2 Duo 3.0Ghz
GPU: XFX 8800GTX XXX
PSU: Coolermaster M700
Hard Drive: Seagate Barracuda 500GB, 7200rpm, 32MB Cache
Disk Drive: Sony DRU-190S (black)
Memory: Not chosen depends on motherboard (ddr2 or ddr3?)
Case Fan: 1xSilverstone Suscool81 Ultra Quiet 80mm
Case: EZ Cool Alpine 7103 (black)
 
So yea comments on components chosen and advice on motherboard to choose greatly appreciated!

Gigabyte or ASUS
any P35 or EP35 Gigabyte or any P5K ASUS
 
Budget? 1394?

Budget: Components chosen so far is about £650 so i'm guessing reasonable mobo will be about £80 maybe? so around £730
 
Firewire: Not a major factor, would be preferable i guess but won't be too dissapointed if not included.
 
Something i forgot to mention, i want the motherboard to be SLI capable so i can upgrade performance later cheaply

Anyone any ideas?
