I suggest that you buy other graphic cards, like ATI HD 5000 series.
Because I am using ATi HD 4650 and I don't recommend you gaming.
ATi 46550 is an ownage card, You just have AGP so you rates are lower than half of what PCI can do
My 4350 is better than your 4650 because its on PCI
Why wont his psu last long o_O
my 350w lasted me 3 years....
PHENOM II X3 710 AM3 CHIP2.6GHZ 7.5MB 95W 4000MHZ PIB
Everything in there is fine for your first dream computer
But trust me you will want to upgrade the psu and get new gfx card after about 5 months lol
Then that becomes your second etc blah blah blah
