I've read on the internet where people have got the K6-2 Plus 450 to overclock to 650MHz (one got 672). Several people have got 622MHz without any problems at all. The 450 K6-2+ has a L2 128MB Cache. I want to get a 500MHz, but the "slower" 450 + has better performance. I don't want to overclock mine, just run it at the stock speed. Will the 450 Plus run at 450, give better performance then the 500, run at 500MHz? I have a 1MB on Board Cache, with the added 128MB L2 on the 450, that will give me 228MB total cache! Will that be better then getting the 500MHZ? I have a hard time buying a processor that's "slower" then what's the fastest I can upgrade to. Thank you, Chris.
