Hello, I was recently given a Dell Dimension 2400 from a friend. It had absolutely no upgrades, however I had old parts sitting around and I gave it a bit of an upgrade. I put in 4gb of ram (however found out it had only supported up to 2gb, so I had to remove a card) and added a Visiontek Radeon 9200 graphics card in. Now, I have two processors here that look like the might fit, but I wasn't sure. So, I was hoping to get a second opinion from someone who has a bit more experience with this than I do. I have two spare processors one of them is a Pentium 4 3.00Ghz (http://ark.intel.com/products/27479...g-HT-Technology-2M-Cache-3_00-GHz-800-MHz-FSB) the other is a Pentium 4 1.6Ghz (http://ark.intel.com/products/27424/Intel-Pentium-4-Processor-1_60-GHz-256K-Cache-400-MHz-FSB) Would either of them work? Also, would upgrading to windows 7/vista increase the support for ram? Thank you.
