As you cannot register you can still read the Matrox Forum. When building a new machine i would leave the rtx2 out. Imo waist of money. How many of the Matrox effects do you really use? I have a i7/940 12 gig ram. I edit HDV like dv, no preview rendering for Magic Bullet Looks, and that counts for something.
CS5 will be coming along and who knows the rtx2 will still be supported.
