Best budget GPU compatible with a 375W Dell PSU?

[eilif]

Ok, i have a computer with a Core 2 Duo 6600 2.4 GHz, 2 GB of RAM and a 7950 GX2 along with a 375W PSU from Dell. And i am thinking of an upgrade, and i want a cheap, good GPU ( PCI Express) with low power supply requirements. I am got in mind the HD 5670, or a HD 5750, both the 1 GB versions.... But i am very open to anything you would recommend, i'd prefer NVIDIA but they seem to be more expensive and power hungry....So, i got a few questions that has to be answered before i decide wether im getting an upgrade or not;

* Will i get a noticeable performance increase?
* Will any of the 2 cards listed work on a 375 W Dell PSU? ( i am already running a GeFOrce 7950 GX2 1 GB, wich requires a PSU with a minimum rating of 400W)
* Are ATI 5-series less power hungry than NVIDIA Cards?
* How long will an upgrade last before it is "outdated"?
* Approximately how many FPS increase will i get? (if i get an increase at all, that is.)

The card is going to be mostly used for gaming, pretty heavy games like Crysis, CoD4 and i will be getting Crysis 2. And the card can't be very big, as i have not got alot of space in my computer... Although the 7950 GX2 is quite huge, i kind of want something a bit smaller, as my case is quite big but already completely STUFFED to the limit, and it has a fanless huge CPU cooler.

Lol im not gett8ing a card until after christmas... But will any of these cards run on a 300W HP PSU along with a Core i3 530 2.93 GHz and 8 GB of RAM and a 750 Gb HD?
I know HP PSU's are garbage, but.... Any chance?

No, i got 2 computers. One with a 375 W Dell PSu along with a COre 2 Duo 6600, 2 GB of RAM and 7950 GX2, and another system, with a 300W Hp PSU along with a Core ie 530, 8 GB of RAM and a HD 5450... The HD 5450 is absolute garbage for gaming, i need to get it changed... Ive changed my mind and the priority is now the 300W Hp PSU

I have Dell Studio XPS that had a 5770 and 350w psu and ran great, but I decided to upgrade last week. I bought Thermaltake 600w psu and Pny GTX 470 and the upgrade was simple the only problem I had was the 470 is huge and power plugs are on the side and I had to move Hdd to upper empty bay and get longer sata cable. I recommend that you upgrade psu first, because with that psu the 5670 and maybe GTS 450 are the only cards I would put on 300w. I only paid $75 for my psu!

yes!
