Short answer: Yes
But where's your processor? Assuming i7 920?
Depends on what all you're trying to do with this build, and buy the looks, I'd say you want a gaming rig with a good amount of power.
I'd personally swap out the Radeon 4860s for a Radeon 5750s or 5770s. Won't take a hit with performance (5770 would be an upgrade), and you'll get DX11 support + Eyefinity (not to mention a slew of audio options running through HDMI).
Otherwise, go for it. Looks like you'll be enjoying some good frame rates for a couple years.
yes i7 920 overclocked to 3.8....but im thinking of going with the asus p6t deluxe v2 now...and the v8 instead of v10..is my power supply big enough?...i went to much over budget cause i forgot to add the i7 920 lol
