I plan to purchase a EVGA 7900GT sometime this week. I currently have a A64 3200+ and S754 Mobo, but it does not support PCI Express, so I plan on purchasing a S754 mobo that does. I have a guy who is buying my video card and mobo, but he would like the CPU as well, even though I could probably get away with not selling it to him. I'll get to the point, is it worth it, from a performance perspective, me mostly gaming, to upgrade to a S939 3200+/S939 Mobo at this point when one year down the road I will be upgrading to Conroe? What are the big advantages S939 has over S754?
