[BravO)))]

Just bought some new gear for my desktop... too bad I won't be home for a while. I will be upgrading from 2 x 2900xt's to 2 x 4850's, and from a x2 6400be to a x4 9950be. can't wait to put them in, too bad I have to wait. Has anyone done any simular upgrades? If so, please list your exp.
