Hi there, I am planning to buy new memory for my system in order to play Heroes of Might & Magic 5 more smoothly on my system. My system specs are as below: Board: Intel D865 GBF Processor: Intel CeleronD 2.40 GHz., Socket 478, BusSpeeed 533MHz Memory: 256MB, DIMM, DDR 266 OS Version: Win XP 5.1.2600 Service Pack 1 Build 2600 Video: NVIDIA GeForce 6600 GT Driver Version: 18.104.22.16872 Adapter RAM: 128.00 MB Please suggest which memory module should I go for. You see, there is quite a jargon about them i.e. 266, 333, DDR, Rambus etc. Further, please tell me which DVD Writer is the best performer while keeping balance between Quality/Speed & Price. Also suggest a good UPS/PSU too(but not an expensive one). Your help will be greatly appriciated. Thanks for reading my post along with advanced Thanks and appreciation on your valuable suggestions.
