Dell Studio 540S SLIM - Graphics card help?


Jul 14, 2011
Hey there, I have done some research and I have found out that my PC is not the best computer to do some gaming on. But I thought I would give it a go, I have so far found out that only low profile cards fit the motherboard, and the PSU is a 250W which I don't want to change. The highest it can go up to is 300W, therefore I don't want to waste the money.

Here are the current specs:
Dell Studio 540S:
Mobo: Dell Inc. 0M017G
Processor: Intel Core 2 Quad 8300 2.5 GHz
RAM: 6GB DDR2 (2x2x2)
HD: Seagate 500GB
Graphics: ATI Radeon 4500 512MB (Low profile) .. came with the system.
Monitor: 24" HD Dell Monitor
(6 USB's & two 140mm Fans)

I've found these low consumption graphics card by doing some research.|cat:13704702|prd:13704702

I mainly just want to run GTA IV on around medium/high graphics.
So what do you guys think about the card? I've seen some benchmark reports on YouTube, it seems to be okay when running without Fraps.
The website it is sold on, claims that the GPU only take 45W on full load.

I may upload some images of the mobo tomorrow when I am out of work, any help would be appreciated, I want to make this quick so I can start gaming. If you have any similar products to offer me with low power consumption and low profile type cards, then feel free to do so.

Here is a review of the graphics card..
If you click on the power consumption section of the review, he mentions that his system only used 203W with Intel i7 + 6GB RAM + The GPU etc..
Isn't that a good sign?
Let me know what you think, I don't have much knowledge on this stuff. Thanks.
