It should be good. Just make sure it will fit

PD: I forgot , what video card are you gonna buy?

radeon x1600 pro

how do i put the cooler on the vid card tho?

Any specific model? Just to make sure if it will fit.

SAPPHIRE 100158L Radeon X1600PRO 512MB 128-bit GDDR2 AGP 4X/8X Video Card

will that work with my comp and the new psu

btw is that "thinking" sound the sound that the psu makes?

First, to install the cooler, you'll need some instructions that should come with it.
Second, the card should work on your machine with a better PSU of course. But are you aware of the X1600 "frezzing problem"? X1600 cards, especially sapphire's (and AGP cards) freeze whenever 3d is rendered. Just check the reviews on Newegg.com and you'll know what I mean.
Third, " a thinking sound"?? What do you mean?

wattaya mean 3d is renderred? i wanna play counterstrike:source. will that freeze it? and as for the sound, whenever i demand stuff from my comp it makes a sound while its doin it. its like a slight-grinding-ish sound.

kind of a clicking but fast

When i say 3D, is whenever your video card renders 3d images, when you play games.
X1600's like to do that.

The sound you say, may be a capacitor, but i'm not very sure. Try to locate where it comes from.

I forgot about the issue with the X1600's otherwise I wouldn't have posted that one. The X800 GTO would be my top choice in the group I sent you, followed by the 6800XT. All of the cards I mentioned will work for what you want to do, though.

The best card would be the X800GTO, is faster than the 6800XT and the X1600 PRO, and doesn't have the frezzing issue.

should i still buy the cooling fan for the x800 GTO?

or should i just run it with the case open on both sides?

I wouldn't think that you would need to go that far. I would skip the cooler until you know if you will even need it. Also, leave the case closed and just monitor your temps and open one side of the case if needed. But if everything is operating as it should, you won't need to remove the panel.

how do i monitor the temp? and at what point do i open the case?

You can monitor the temp using Speed Fan or Everest Ultimate. Software temps aren't very reliable, but they give you an idea on how hot the pc is running.

I would open the case when my CPU temp reaches 60°C or the case temp is above 45°C.

And I think you don't need a cooler for the X800GTO. My particular card came with a good cooler. This is the cooler I've got, but this is a Powercolor PCI-E card, I'm not very sure about the AGP one.
