Phenom II x2 555 BE or Athlon II x4 640?

post #1 of 21
Thread Starter 
Which CPU would be better for gaming? It will be run with a gtx560 (non-ti) and a 500w modxstream pro.

thanks

555 because of the L3 cache and most games still being single/dual core encoded.Also it can reach 4GHZ pretty easily which increases gaming framerates. Strong possibility it will unlock to a quad core as well. If unlocked to a Quad it is perfect for a dual gpu setup as long as it isn't something like 2 6970's.

640 isn't a bad second prize, it does really well for popular games like StarCraft II/COD/BC2. However it is really hard to get it to 4GHZ and it has no Level 3 cache(which doesnt matter at all for alot of games but still helps at times). Also its not recommend to use on a higher end SLI/Crossfire setup as a bottleneck can occur because of the lack of level 3 which helps in dual gpu setups.

A Phenom II 555 basically competes with the Core 2 Duo e8400. If unlocked it competes with a Core 2 Quad Q9550.
An Athlon II X4 640 competes with the i3 540.

Overall either is ok, I prefer the 555. Alot of people will get the 640 because it is a guaranteed quad out of the box.

check the following link for more details about the difference between the two

Yeah they would be pretty close for the reasons dlee mentioned. I would choose Athlon II 640, but can go either way.

Ok i think il go with the phenom but is there any chance it could bottleneck my graphics card?

fill out your system specs, and we can help more, memory and mobo will determine this a little. I have an unlocked 555 at 3.9ghz, running 2 460's, which is almost identical. (when sli is off) SLI on I can run close to anything at maxed out settings @ 1080p. metro 2033 is a little choppy maxed out though.

If you're going to run the 555 unlocked with that board, expect problems down the road (specifically with the VRMs and a Phenom II x2 unlocked having the same high power consumption of a Ph II x4). You should either swap the board or maybe take the Athlon II x4 (lower power consumption to begin with compared to Phenom II x4)

Could i run it with 2 cores for now with that board? Il get a better motherboard in the very near future when i have more cash.

Yes, that would be a good idea.

you need to also add that as long as you are not overclocking the unlocked processor alot then there isn't a real problem.

The people who try to get 4GHZ on a lower end board without the proper MOSFET/VRM cooling are the ones asking for trouble. Similiar to a dude on a 4+2 who was testing out a 4.3 GHz overclock and burnt out his board.

My unlocked X4 at stock is 3.2 and I have it overclocked to 3.5 and its perfectly fine.

Overclocking while locked seems quite fine as x2 consumes much less power. For any x4, you will want to look to at least a 4+1 phase with quality design & stable operation, and proper cooling.
In your case dlee though I would definitely look out and watch where you're going, that's actually a 3+1 phase motherboard you're using; 3+1 phases regardless of brand, even cooling, often see problems running any sort of power-hungry processor.
