Dell PSU and GPU question

I'm going to check out a computer which I saw on craigslist recently.
He posted it as a dell which he recieved a couple monthes ago for 1400 w/monitor.

He doesn't know the model/specs, so I just figure I'd go over and check myself.
I looked at dell's website, and many of their computers use 4350 graphics card.
My question is, if I get over there to find it has a good specs, other than that, how far am I likely to be able to upgrade, as in, what is the nicest card I can buy, that a dell computer can power?

I would say 80-90% of them are mediocre power supplies at best and it would be surprising it would run a good video card.

I don't trust pc manufactures and the components they put in them. You might as well have the mindset you have to upgrade it and if you don't then you are 1, lucky and 2 did I say lucky?

I wouldn't count on being lucky.

Check the +12v amps and the wattage.

Dell has very nice PSUs in their systems, but they are a bit low on the wattage for really high end cards. Their 375W can actually handle a pretty powerful card - you could definitely run a 4850 on it, but the 305W might have some trouble. It's a darn good 305, but you couldn't run a really high end card on it.

I OWN 2 DELLS AND I AGREE THE POWER SUPPLIES ARE BARELY ENOUGH , NOT NEARLY WHEN YOU ADD MORE COMPONETS.I AGREE CORSAIRS ARE NICE!!!!!

NO DELL IS WORTH 1400.00

1. I think your caps lock is broken
2. You could not be more wrong, although I agree you can build a better system with the money I would have no issue using any of these computers. You also forget the computer comes with a monitor.
