Core 2 Duo 2.13Ghz vs Dual Core 3.4Ghz

[Guest]

Hey,

im considering upgrading my system, i have read many reviews on the web about which cpu to buy and it appears core 2 duo seems to be considered the best at this time. but through reading many of the reviews apparently the core 2 duo's arent great for running games and that single cores or the older dual cores are better. Although ive been on some graphic cards review sites that have run benchmarks and the systems with core 2 duo 2.13 (E6400) had better frames per second etc than a dual core 3.4Ghz, therefore this conflicts with other reviews. This has left me confused as to which is really better. I realise there is more to cpu's than just the speed but would a E6400 really be better than the dual core 3.4Ghz? plus i can get the dual core 3.4 for £100 but the E6400 for £140 does this price difference effect which is more worthwhile?

Thanks

E6400 is really better a Pentium D 3,4GHz.
