I am debating wether to get the new evga 660 Ti SC + 3 gig ram or the regular 670 with 2 gig. Price difference is about 50 bucks; but I only have a 500 watts PSU that came with the case. Its a Sonata 3 PSU

The site Im getting it from recommend to have +12 Volt current rating of 30 Amps for it. My PSU says 24 Amps. Anyone have this card with similar PSU and it works fine? Or should get the 660 instead?
