Thank you all for your thoughts and imputs! I think I will look into a more powerful Vid card. I want one with at least 1gb of memory though. Any ideas where to start there?
Hmmm... I think if you want more video power, you'll have to consider changing your motherboard as well. Newer cards that come to mind like this and this already support PCI-e 2.0, and your motherboard needs to change so that you can maximize that.
