That's not really an upgrade. As I said, you *can* run the power supply with the GPU, but now that you're using a >$300 GPU, I'd want to move up tiers. What's the best buy depends on where you are; while Newegg has the Corsair CX 550m right now for $35 with rebate, given that you're using a VS, I'm assuming you're not in the US. Don't get me wrong, the VS isn't Fry Everything with Fire bad as PSUs go -- we see a lot of these -- but I think you have a good argument for a quality upgrade unless the budget is just too tight.
