PLEASE READ and HELP.

Your 375w, 30a PSU should be fine adding a 7600 series card. My best AGP cards are an x800GTO and a 6600GT. Both run 1440 x 900 on 19" widescreens. The 7600 series should work well on what you have.

okay, im thinking i might buy a 450-500 watt psu, and then buy a 7600gt 256mb on newegg for like $119. I just looked in my computer, it has a 305W, so i definetly need to upgrade that. Im really doing this for gaming, because my FX5200 isnt a real good performance card for gaming and fps. I normally play call of duty and call of duty 2, and i get like 70 fps in call of duty 1 on 1024x768 on high settings. On call of duty 2 i get like 30 fps. I wanted to get a card to make it atleast 200-250 on call of duty 1, and atleast 60-80 on call of duty 2

Why don't you buy the card and try it with what you have. The 7600 doesn't use a direct 12v power supply source, it draws power from the MB AGP slot. You better check around, some people have run into problems replacing the PSU's on Dell systems. I've never owned a Dell, so I'm unfamiliar.

how about this 7600GT, its low priced, and has some good reviews..

That is excellent, I might buy one myself! Yeah, that card wouild be a major boost in your gaming experience for sure. And you can probably just install it in your system without changing the PSU. I would say go for it.

BTW. I installed a 7600GT PCIE for a kid months ago. He plays organized gaming competively all the time with it. For him, it was the perfect choice.

I noticed that 7600GT has a 4 pin 12v power connector. So, you could run into a PSU problem depending on how much power draw the rest of your system has. You mentioned 512MB RAM and one hard drive? Not excessive power needed for that. I would give it try with what you have.

Nooooo. If you're going to buy a new PSU, get the X1950GT. It's the same price as the 7600GT, and it'll kick the living $hit out of it.

yeah the 7600GT does kick some ass, my brother has the pcie one and it just screams, sometimes he gets too much fps and looses connection lol. but anyways. Should i risk taking 7600GT and not a new psu, or should i get the psu, and get the X1950GT?

If it's not going to break your bank, I'd go for a new PSU and the X1950GT.

i think im just going to actually get the 7600GT, so i can save about $100 for my next rig in about 2 years. im going to overhaul it, and get all the bells and whistles later on. but i think i am going to get that 7600GT. it does make a diffrence when u play with a FX5200 128mb card. and u lag alot too when u are in smoke. so ill look forward to that.

that and also im in this league for call of duty, called nagl, so i really wanted to get a new card so i can kick it up a notch there.

You should take a look at the specs on your 305W PSU to make sure it'll supply the 18amps on the +12V rail you'll need for the 7600GT.

im not sure though. people are saying go for the X1950GT, and get the like 450-500W psu, so you dont have to worry about the watts drawn. But this happened on my dads computer when i got a video card for him, he has a 300W psu and i put a card recommended 350W, and it drawn in to much power, and our internet kept loosing connection, so i might actually go for the psu and card.

yeah im going to try that out, and see what i can find with the X1950GT, and the psu, can you help me find a psu on newegg?

Well, if you open up your case, the specs are listed on the side of your PSU. Take a look at the +12V amperage. If it supplies at least 18amps, your fine for a 7600GT, if not buy a new 450W PSU with 30amps on the +12V rail, and get the X1950GT. It would just suck to buy the 7600GT, only to find out that it doesn't work with your current PSU. Then you're stuck buying a new PSU, and not getting your money's worth out of your GPU.

what kind of psu should i get?

This is the one you linked in your other thread, and it'll work fine with an X1950GT.

its either that or this

I'd stick with the first one.

alright so im most likely going to get the X1950GT, and the FSP 450W psu. so thats pretty good. do u game?

Yes, but not too much lately. I've been having over-heating issues. Not a big deal though... I'm just about ready for a new build.

what games u got?

FEAR Extraction Point, HL2 Ep1, STALKER, Quake 4. Those are the one's I have yet to finish.

This link may be of assistance also.

What psu do you have now?
Which Dell system do you have?
If you do indeed have a DELL 305w psu the specs on it is 22amps.
