Hello, I'm trying to rebuild a computer for the first time because I've recently gotten into some Higher end gaming. I want to be able to run windows 7 beta (I've heard its pretty light and am interested to check it out). But my main reason for rebuilding is gaming. If anyone has time to help me choose which parts must be replaced and which parts they should be replaced with I'd greatly appreciate it. The cheaper I can get this thing running good games the better. Here's my current setup: Gateway E-4000 Intel Pentium 4 Processor CPU 2.00GHz 254Mb Ram DirectX 9.0 currently (It'd be cool to run DX10 if its not going to be too far outta my price range) Graphics: NVDIA GeForce MX 440 128MB memory. 32 Bit @ 1152 x 864 resolution SoundMAX Digital Audio (sound) P.S. if its possible to replace parts 1 by 1 with those most important first that's how I'd love to do it. Thank you!
