well i meant better really for the graphics card. take a look at this thread which is stickied at the top of this subforum.
Graphics Performance List
to give you an example, you had picked a 9500 gt, which is ranked at #50. the 3870 i suggested for you is ranked at #27. all the cards are listed according to their performance, #1 being the best, so pretty simple to figure out the rest.
as for the psu, having a higher wattage psu doesnt make it better, especially if they arent from a good brand. i dont know how good ultra psus are, but i do know that corsair is one of the best and you dont need 650w. that 400w psu i suggested will have plenty of power for your rig, its the amps that matter more than the wattage.
plus, i was trying to stay within the same amount of money you were spending on a psu and graphics card. im assuming you chose those because you have a set budget in mind. those are better options though.
