I have a new 5750 to go with my 5850 but I'm defiantly going to need a new psu first, probably at least 550 watts on the same rail and I'll pass my old one down along with a 9800gt

.
I really like the Thermaltake Toughpower ones cuz they look nice and beasty but theres always deals on these APEVIA ones so I don't know which one to get. I imagine these would be good for around the same amount of power but if I paid the extra $20 it would be more reliable, efficient, and its modular, maybe worth it in the long run? If you have any other suggestions lets me know. thanks
