Graphics card for an old desktop

I honestly do not know much about computer hardware. I apologize in advance if this post sounds illogical or impossible.

I have a rather old desktop, hp a6040n, in which I plan to acquire a graphics card to run some modern games. The recommended requirements of said games are shader model 3.0, 512 MB, GeForce 8800/ATI X1900. The current power supply is at 250 Watts. I understand that I probably need to get a power supply unit as well. Perhaps, a new system is a better idea, but I am not prepared to shell out for another system at the moment. Which graphics cards and power supply that are currently on the market would you recommend, if any?

You should be able to use an low-to-mid-level AMD Radeon HD based board without upgrading your power supply. The 7750 models are the most powerful that only draw power through the PCIe slot - no need for the 8-pin power cables.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

My only concern over the 7750 model is that it specifies PCIe 3.0 - not sure if there could be some incompatibility with your older HP's 945G-based motherboard. (Per Wikipedia, should be backward compatible - http://en.wikipedia.org/wiki/PCI_Express#PCI_Express_3....)

Another option (which is quickly disappearing) is the Radeon 6750 models with GDDR5 memory. About the same price as the 7750, likely a little slower, but also plug into a single slot without extra power cables required.

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

The 6750 boards are specified as PCIe 2.1 compatible, which I suppose would be more likely to work.

Either one will set you back a bit over $100 (US) and far exceed the specs you provided. You will probably be limited by your CPU performance rather than the video card... (is that a Core 2 or a Pentium?)

I hope this helps!
