I currently have a P4 2.8 GHz running at about 3.0 GHz in my current system. I picked up Doom 3 recently, and realized that my video card could use an upgrade. Sadly, my current motherboard (MSI 845 Ultra-ARU) would hinder the performance of any card I get since it's only a 4X AGP board. I'm now thinking about upgrading my motherboard and keeping the same non-HT P4 CPU in there as my CPU speed is absolutely fine. I was just wondering which board I should use since I would like to have future upgradeability. The Asus P4C800-E Deluxe looks incredibly good to me, but I'm not sure if my current CPU would work in there. If it would, then hell-yeah that's the board I'd be getting. I also want to be sure that putting my current CPU in there wouldn't cause any problems in terms of functionality. Sorry for the not-so-coherent rambling of this post here, but it's kind of late. heh. I'd appreciate any advice I could get. (My rig can be found in my profile).
