No, I don't think it's too old at all red. I have a Dell desktop that's over 14 years old and it runs the game okay.
I have been on intels website and to the best of my knowledge the latest graphics driver for your CPU is on this page. You can either click the link for the driver download here win64_15.40.47.5166.exe or click the download link on the webpage itself, they are both the same.
Once downloaded, locate the file in your downloads folder and double click it to commence the installation process.
If you wish to ask others for confirmation as to whether this driver is the correct one, please do. The more people who okay it, the better, as far as I'm concerned. But I am also sure that if it was incorrect, it just wouldn't install and it does list your CPU at the bottom of the webpage.
Cheers for the info red and if you don't want to install it, I have no problem with that decision either. ; )
