I have a Dell desktop computer with a 256 MB Nvidia 7800 GT/Pentium 4 3 GHz/1.5 GB RAM/520 watt OCZ Powerstream PSU. I would like to bring it up to my dorm, but would have to put it in a more portable case. Because of Dell's proprietary standards, this would entail getting a new motherboard. Here are my options: 1. Keep the Pentium 4 CPU and get a new motherboard. This would be my cheapest option. 2. Switch to AMD and get a new CPU as well as 2-4 GB new RAM. The CPU I had in mind was the Athlon X2 5000+. http://www.newegg.com/product/produ...hBargains-_-NA-_-NA-_-NA&Item=N82E16819103194 This is the case I'm looking to get: http://www.xoxide.com/lianli-v350b-microatx-minitower-blackcase.html Is the Pentium 4 still fast enough for gaming, or should I get the AMD? Is there a better alternative for a cheap gaming CPU? My budget is $300 or less for the CPU/Mobo/RAM together. I mainly play games like BF2, Civ 4, and Oblivion, but plan on trying out a few new ones like BioShock or Grid.
