Anandtech have an excellent guide on selecting the right midrange CPU for your PC based on both benchmarks and overclocking ability (if you are willing):\n \n[quote]AMD and Intel are unbelievably close when it comes to mainstream CPU performance - far closer than we expected. There are a couple of exceptions, however. DivX encoding in particular is extremely strong on Intel CPUs where AMD just can't compete these days.\n \nIf you're choosing between the Athlon 64 X2 5000+ and 4800+ definitely go for the latter. The performance difference is so small that we don't even understand why AMD has both speed grades. At the 2.5GHz+ clock speeds we're talking about, 100MHz differences don't amount to a significant enough performance difference to justify any increase in cost.[/quote]\n \nRead the article [URL="http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3112"]here[/URL].
