forget dual cores... thise days it just isnt the way to go... they have no future... so forget the athlon x2
then forget first generation phenoms... they arent that bad for the money... but in the end buying an AM3 system today is just a better choise for the future... new Cpu's comming, DDR3, just a lot more upgradability...
in the athlon x4 and the phenom II x4 it depends on what you need your computer for... if you dont need a lot processing power or are on a tight budget you should go to the athlon x4, but if you do some gaming or just think that you might need the extra horse power go for the phenom =)
on the board side take a look at the GA-MA790FXT-UD5P from gigabyte... i have one and its a superb motherboard full with nice features
The original Phenom are pointless, they were good for their price until Athlon II X4 was released. Since DDR3 and DDR2 ram cost similar now, and the boards for the 2 are similar, you should just go with an AM3 system. It'll give the best performance and be the most future proof upgrade path.
If you're looking for a budget CPU, then the Athlon X4 620 or 630 is a good choice. It's basically the same as a Phenom II without the extra L3 cache. The Phenom II will scale better when overclocked otherwise, it's pretty much the same. I believe they are actually Phenom II rejects re-badged as Athlon X4, just like how the Phenom II X3 and X2 are just rejects of Phenom II X4.
Hi! Thanks for your help. I will buy an AM3 socket. I will choose between the phenom x4 and the athlon II, depending the final cost
I asked about AM2+ because someone said that it has the performance near AM3 and it's cheaper depending the store.
if you are cost sensitive you should probably just check out the athlon ii x4 620 and the phenom ii x4 945... the 945 should be around doble the price of the 620 a little less, you wont get almost twice the performance, but it should be a noticeable diference so you might wanna invest in it since its better to have and not need then need and not have =)
