I would like to upgrade my video card but am confused about which to buy. I have an older system and don’t what to through money away on a fast card if my system will not benefit from the increased speed. I don’t know at what speed my system will bottleneck a new card and be wasting the extra speed and money. I am looking at two different video cards the Galaxy, GeForce 9500 GT, 1GB 128-bit GDDR2, PCI Express x16 or EVGA, GeForce 9800 GT, 1GB 256-bit, PCI Express 2.0 x16.
My rig is a Gateway 840GM with a Pentium D 830, 3.0 GHz, 800 MHz FSB, 2MB cache, Level 2, and running 4GB PC4200 DDR2 SDRAM, and EVGA GeForce 7800 GT 256 MG.
Thanks for any help.

You are aware that the 9500 GT, 1GB 128-bit GDDR2 have the similar speed with your 7800 GT 256.

The HD 4670 is the best card for your system.

What is the resolution of your monitor? What is the power supply? What are your expectations? What is your budget? Where were you in the night of the 5th?
The HD4670 is going to give a nice boost, but may not give the results you want.

I have a 32 inch widesceen LCD with a native resolution of 1680x1050 and a 400watt power supply. I am some what open to price but want to make sure it will not over power my CPU.

Any GPU will over power your CPU. Bottlenecks are not hard, nor linear in a comptuer system. Short of a high end SLI/CF setup you have plenty of CPU power to get some scaling out of any GPU setup. That is to say a more powerful card will still give you a performance boost over a slower card, it just isnt as large a boost as someone with a high powered CPU gets. Even in a severe bottleneck a more powerful GPU would allow for higher AA.

That being said, in order to maximize the investment, and given that there is no point in getting a powerful GPU if your CPU doesnt meet requirements of games. The best card for you would probably be a 4670/9600. Any more and it would be of questionable value as far as price/performance goes.

@ MajQball: The Hd4670/9600 is about right, as the others have said.
If you want to push a little more the HD4770/9800GT pack more punch..
Note, both the HD4770 and 9600GT will require a 6 pin PCI-E power connector as will the 9800GT. Ignore the 9500, even with 1Gb it's not in the same league as the other cards.
