Looking to start building a new computer and it's main application will be for games. I've been out of looking at hardware for a LONG time so I don't know a lot of this stuff anymore. I've been looking at AMD and Intel. How do the AMDs 64-bit processors compare to the Intels that are out there? The main reason I'm asking is AMDs seem to be running a good bit slower. Say I have a 2.4ghz 64-bit AMD and like a 3.2Ghz Intel... How do they actually compare to each other Performance wise? Also, tell me about these dual-core chips. Say I have two chips of the same clock speed. One is Single-Core and one is Dual-Core... Is there truly a difference between their performance levels? Does the computer automatically take advantage of the Dual-Core technology or is it something the software has to support like dual-processors? Thanks for the help and I hope that all makes sense.
