Hello everyone. First off I would like your guidence\preferences on these things when buying a new PC for games like Half Life 2 and Doom 3: wich one should be sufficient a AMD Athlon XP 2400/2600/2800/3000 with Quantispeed Technology. 512mb RAM or 1024mb RAM (both are PC 2700 DDR 333mhz) A 120GB Ultrafast with 2mb buffer or 120GB Ultrafast with 8mb buffer (both are 7200rpm). A 128mb ATI Radeon 9600 with TV out and DVI or a 128mb NVidia GeForce FX 5600 with TV out and DVI or the 256mb version of the FX 5600 stated before. These are the only things i'm stuck on as i would get the better ones but i may be wasting money so i thought i'd let you guys choose for me. Thanks for the help in advance.
