First here's the problem...I have a 2001 Gateway E4600 ATXSTF (that was given to me)...Memory 256 MB, Intel Pent 4. 1300 MHz 100MHz external bus...BIOS is Default System or Intel Corp...Video ATI Rage Fury Pro Xpert 2000...Soundcard is completely smashed but I think it was a Legacy...had Windows NT then I upgraded to XP which took up all of the memory...yeah I know I should've checked the spec requirements first but....oh well. So I've been struggling with either upgrading this system or just building one. From what I've seen online at different sites, this particular module is not good for upgrading...especially by it being manufactured by Gateway. I know that I need atleast 2GB or more of memory and I want 500- 750 GB of Hard drive space. I'm a graphic designer and dib and dap with music production. The main programs I will be using is Adobe CS3, Fruity Loops (FL Studio), Reason, Acid Pro and Cool Edit Pro. Also I will need the ability to record from my DJ equipment and Keyboard (midi). All of the computers on the market now lack atleast one thing that I need. I'm not feeling having to work with Vista and would like to keep my XP SP2. The processors that I'm looking into getting are Intel Pentium Dual Core E2140 1.6GHz 800MHz 1MB S775 CPU or Intel Core 2 Duo E6600 2.40GHz 1066MHz 4MB Socket 775 CPU. I know I will need a 500 - 600 Watt PSU for either one. But I don't know what parts would be compatible. I've been looking on Geeks.com for items as far as Motherboards, Memory, Video and Sound cards. This will be my first build so any suggestions would be highly appreciated!
