which CPU is better ?

Better get a dualcore like the opty 165 or X2 3800+, games are seriously going dual core.

not true that you need to get dual core but yes it could be recomended(depending on your requirements).

Though out of the two you said I'd go for the opteron144 it overclocks well (considering you have good motherboard, ram etc)...

NewEgg has the Opteron FX-55 at 2.6GHz for $139...

Enter promo code AMDRocks

Or get a FX-55 with free a Seagate Barracuda 7200.9 ST3250824AS 250GB 7200 RPM SATA 3.0Gb/s Hard Drive for $209...
That makes this $25 cheaper than the other deal, if you need a 250GB drive too.

alrighty thanks.

someone have a link of X6800 and 5160 woodcrest?...
i dont see woodcrest in the cpu charts here...

woodcrest won't be on there tho heres the link:

RichPLS, how do you come up with $25 less?

1. FX-55 Promo #1 - $139 and HDD - $75 -- Total is $214

2. FX-55 Promo #2 - $209 with free HDD

This is only a 5 dollar difference. With the first promo, you need a heatsink/fan. Is this where the difference is coming from? What heatsink/fan did you pick?

Though, personally, I'd just get the $139 FX-55 with the Seagate Barracuda 7200.10 250GB Perpendicular Drive for 5 bucks more, here.
