i am thinking about getting a computer with amd processor in it, but just curious what the equivalent is compared to intel, since i am more familiar with them. what would be comparable to the amd athlon 64 3500+ (the pentium 4, celeron, etc.?), and also for the amd sempron processor 3200+? thanks for any helpful info.i want to know what the amd processors are compared to intel's. for example is amd athlon 64 3500+ equal to pentium 4 or celeron?
