Hello, here goes for my first post on techspot. Recently i have been thinking about upgrading the computer or saving and getting a new one. I don't really play that much games for the PC but recently bought C+C3 and love it. Someone suggested buying a new graphics card instead of going to too much expense. I'll be honest this is a big grey area for me just now and need some advice. First off here is some of my specs: Computer Name: Dell Dimension 8400 CPU: Intel Pentium 4 640 (3.2ghz with HT) Mainboard: Dell 0U7077 Memory: Type - DDR2, Channels - Dual, Size - 2048MBytes Graphics Card: Nvidia Geforce 6800 256mb PCI Express Hard Drive: 250gb SATA 7500rpm Monitor: Dell 1905FP Operating System: Windows XP Professional I opened up the tower and looked at the back to try to find out some power supply information and unfortunately couldn't find any. Maybe someone knows this system better than me. I have only upgraded the dvd writer and memory since purchase. According to the manual "PCI Express cards that run at 75w or higher require an additional cooling fan". I enjoy playing first person shooters and games like C&C3. 1) Is it worth while upgrading or just be patient and save for a new PC? 2) If i upgrade what would be a decent card for my system and would i need anything else apart from card. Thanks in advance for any advice posted.
