Here's what I'm looking at in my price range:
CPU #1
Athlon 64 3200+
2.0 Ghz
2000Mhz System Bus
512KB L2 Cache
512MB PC3200 DDR memory (Can be upgraded to 4.0GB)
CPU #2
Athlon 64 3500+
2.2 Ghz
2000Mhz System Bus
512KB L2 Cache
512MB PC3200 DDR memory (Can be upgraded to 4.0GB)
CPU #3
Pentium 4 processor 630 (64 bit)
3.0 Ghz
800Mhz System Bus
1GB L2 Cache
1GB PC3200 DDR memory (Can be upgraded to 4.0GB)
Since we use the computer for everything from word processing to photo editing to gaming, I intend to add a 256MB graphics card in the future, no matter which I go with. The AMD choices, I intend to double the memory to 1GB.
Which system would be faster and more powerful?
I have heard that processor speeds with Athlon 64's are not measured the same as Pentium 4 processor speeds. In other words, a 2.0GHz AMD processor operates at a similar speed as a 2.8 P4 processor. I have also heard that the Athlon can be tweaked or "overclocked." (Although it seems to me as if that would dangerously overheat the processor)
What advice can you give?
