I've seen some pretty nice looking systems on the Deals page that are really tempting me to upgrade my system (P3 1.0 GHz). I do have a couple of questions though that I hope you guys can help me with: 1 - Looking at the Dimension 8400 with the Intel 925X mobo. Is this a good mobo? 2 - I'd probably stick with 512 MB RAM for now, but is it worth the $30 to get the faster RAM? 3 - I'm a bit leery of the video card in the system - the Radeon X300 SE PCIe x16. I currently have a GeForce 5600 with 128 MB RAM. Is my current card much better than the Radeon? I might come back with more... Thanks in advance.
