View Full Version : Performance difference between two CPU's

06-06-2011, 09:49 PM
Im building myself a new computer and was wondering what CPU to get. So I know Im getting a AMD CPU and was just wondering if there is much of a performance difference between the AMD Phenom II X2 555 3.2GHz Black Edition Dual-Core and the AMD Phenom II X4 840 3.2GHz Quad Core?
There's only $30 difference between the two. I will be using x64 version of Windows & so hopefully using the quad core will increase performance a bit.

So if anyone has any advice to which one is better or whether the quad-core will be better their advice would be much appreciated.

for $30 two extra cores is worth it in my opinion. In multithreaded applications or even if you like to have a lot of things running at once the quad core is much nicer.

The black edition is for overclockers really but even overclocked it is still 2 cores down.

Of course I think you're crazy and should either wait for bulldozer or build an i5 :P

If you're building a budget gaming machine, the X2 BE. Anything else, the X4.

Id rather get an i3 if going budget $167 v $134.....
i3 is all over the X2 like a rash, and thats at stock!

the i3 also beats the x4 btw, and in some cases the x6

Cheers for your help. I would like to get an i5 bt dont have much cash ta spend so just settling for a AMD x4 at the moment. I just need something to be able to do some Photoshop on and convert music, dwnload stuff and a little bit of light gameing so not going all out on a comp yet. So I think il settle on the AMD Phenom II X4 840 for the moment.
