I know someone with Dual 6800Ultra OC extreme editions, rig cost bout the same as my truck, but....
NEVER DROPS FRAMERATE!!!!!
My next board will be a PCIx16 one so I can SLI
but, I would use that procesor, or the 3200+ 64 bit one
real close
also for the video card, the 68xx series handle AA and AF better ( obviously due to 2x the bit ) as the 66xx cards
but, its really a price issue
get a 550 watt system if you will be running that proc, 1-2 vid cards, and youll need some NICE fans
and, get the gig of RAM in dual-channel
Sound card, get an Audigy 2 gamer
best one out there for the price, and comes with many games
Speakers, If you can afford them, get the Logitech Z-680s
Bass perfection.....
The Z-640s aint bad, got mine for 48 with shipping, but they dont sell anymore, have to buy them from private seller
Your gonna have one bad ass game rig if you do the above
