For the next update to Aces High, this will not be quite true. If you are in the neighborhood of 3Ghz, for the CPU, then a video card upgrade could be the ticket. Just make sure your new card has 2GB of dedicated video RAM, or more, if you want to run with max eye candy.
Groovy baby.
Looks like with an OS and video card upgrade I may be able to extend the life of this old gal a bit longer.
This has easily been the best machine I've ever had or built.
