Honestly, I would have gotten a cheap Intel motherboard and gotten even a basic Core 2 Duo dual core. You can make it work, but I'd suggest a better motherboard/processor combination.
Newegg link to your motherboard. Read the reviews. Seems like it can be finicky at times. It will be able to handle everything else you want to put in your system. But, no way are you going to be able to play either of those games on full. Medium at best is my guess.
You'd need to get at least 2 GBs of RAM. What OS are you planning to use?
