nb: keeping old soundcard (soundblaster) and old gfx (7950 GT)

Aiming to push my Q6600 to 3.4Ghz, and still be capable for the 4780HD when I decide to upgrade. I did some calculations and, if I did it right I think 650W should be ok for the time being...

With my current GFX I got a value of ~450W, and with a 4780HD I got ~540W, and this is at PEAK load so it will usually be much less than that.

This is all theory though, something which completely ignores the degradation that happens as PSU's age... thats why in say 1-2 years time I'm not sure if my PSU would handle it all so well, and why I'm thinking of going 750W TX.

Thoughts?

If I mucked anything else up or you have recommendations now would be the time to tell me.
