Silverstone Zeus 520w, match the best pci-e card...

I have a abit nf-95 with a dvd burner,1gb corsair xms, 320gb sata hd,165 opty powered by a Silverstone Zeus 520w power supply(set up for SFF in a micro atx case).The psu has a duel 12 volt rails 12v1@16amps,12v2@15amps at 375w on just the 12v's,whats the best video card to match my system without changeing it out(as we know how power hungry todays cards can be).I was looking at the 7800 and 7900 gtx's,would their power consumption be to much for this psu(looking for long lasting reliable service,as well as an excellent gamer...cs,hl2,css,battelfeild2 and some new games but not real concerned with dx10)?Any feedback would be greatly appreciated,thx. p.s. Should I wait till the r600's and 8900gtx's come out and really drive the price down.

Oh come on, cant u give him a brake just this once? Hes so close to 32A!

Kudos to you(mpilchfamily) for all you've inclined the average joe,where would they be without your important info(saved thousands of us from spending costly hours on the net finding the input ourselves)which I've read most of.
I was just looking for someone with a simular setup that had a long and prosperious PC(I would like to play games,as I said before not necessary to play dx10,but in the best eye candy possible with staying in my perameters).So if your running an x1800xtx,x1900xtx(or xt),7800gtx,7900gt,or something simular let me know(with a simular setup).And again ,thanx for all the input from everyone .
