hello i have a question about a power supply.. i have an AM2 motherboard (K9Neo-F), with 2Gb Ram (667Mhz), AMD +3000, a Geforce 7300Gs, and one HDD 80Gb.... i bought the most "Heaviest" and affordable, for me, power supply (680W, i think thats the max output). its not a thermaltake nor a quality brand, just the most affordable... i want to upgrade this configuration..... with this config i can play call of duty 4 with medium to high settings, (excellent for me )... i'd like to remove the 80Gb HDD and add two HDD 250Gb each, besides i want to replace the cpu with an AMD 4200x2...

the main question is what video card should i buy??? im looking for a 8800Gt... or maybe a geforce 9 series... but i dont know if my power supply can handle that upgrade..

these are the values from my power supply lines: +3.3v (35A); +5v (50A); +12v1 (17A); +12v2 (18A) ; +5vsb (2A) ; -5v (0,5A); -12 (0,8A)...

PD: i have an energy connector (6-pin) for pci-E video cards...

i Hope someone help me.. Thanks...
