I realize that they are not the best PSUs on the market and that the 12V rail's amperage rating is borderline. If he wants to save some money right now, then he can try the PSU. If it works...and it very well may work...then he can upgrade the PSU when he gets the second GPU. I have an overclocked X1800XT and 3200+ running on a NeoHE 430W - completely stable. With his setup, I would think that he will max out with a draw no greater than 300-350W. He may be borderline with on the 12V rail, but if he gets the GPU/CPU on separate rails, then he should be good.
