1.what can i overclock the e8400 to?
2.No one still said if all the parts are compatible with each other
3.Is the e8400 rly a good processor for $203.99 (performance:cost ratio)
1) I think people are hitting 4Ghz with these. Is a x9 mutiplier, so at a 400 bus you are at 3.6Ghz which would run DDR2 800 in a 1:1 ratio. If you want 4Ghz I suggest faster RAM since you will be at a 445MHz bus.
2) I did say "everything will work"
3) Absolutely. You won't get a quad to hit 4Ghz like the e8400 will. I guess it depends on what you are doing with it. For games YES, the faster clock delivers better performance on most games over a quad core that runs slower. If you are running alot of apps that take advantage of all 4 cores, then maybe a quad is your cup of tea.
