Gaming Lags

I am reading reviews and
http://www.techspot.com/review/24-radeon-x1650pro-vs-geforce-7600gs/page2.html

I know there is a 7600 in my laptop, if that's what you bought for power comparison, I got to wonder what you are trying to play. It also makes me wonder if you accidentally downgraded cards...
-Edit, I just noticed you said DOTA, I assume that's a game name?
is this it?

So unless you can give a bit more information on your circumstances,

if we assume this card:
Is capable of running the game you want to run.
Is in fact an update from your old card.

And we assume the game in question ran on the old card.

Its possible you are using your old cards drivers to run the new card. Make sure you delete all your video drivers before installing the new ones. You can accomplish this through device manager. Delete all your display drivers, restart your computer, don't let windows auto detect the display, and install the new drivers.

Let us know if you need help with this.

I just googled that DOTA name I found.
128 MB RAM, 8 MB Video RAM, 550 MB disk space

Sounds 2D?

if so, I would not be surprised if it runs like crap, modern video cards have a hard time with the older directX. I noticed this especially bad on every nVidia card I've used 8000series +, I never tried an ATI card but it would not be hard to believe it true. The last one I used was a x600 in my school laptop... which did a terrible job in 2D games, but it performed well in 3D games and particularly liked OpenGL games. It did well in DX3 and DX4 games, fell on its face in DX7 games. By that I mean it was almost in second per frame it was so bad...

The Amount of RAM on it as well as the OS that it is working with are also required.

As you are running a ATI Radeon X1650 AGP Card the features of the Chip Set are

Without knowing what the M'Board that this is plugged into as well as how much RAM is on it, it is impossible to even guess what is happening here. But as it is AGP you need to look at the Speed of the AGP Port on the M'Board if it is 1X or 2X and you have a 16X AGP Card then I wouldn't expect it to work as well as a 2X card that was previously fitted. Mater of fact I wouldn't be surprised if it didn't fit into the M'Boards Socket. A 8X AGP Card will function much better in a 8X Socket than a 16X Card could. ;)
