AMD Phenom II X4 840 any good?

post #1 of 7
Thread Starter 
http://www.ncix.com/products/?sku=58...anufacture=AMD

I finally finished my basement and now will be building myself a HTPC\\Gaming system hooked up to a plasma TV.

I know I need to spend most of my money on the video card if I want a good gaming rig, so I'm trying to cut costs any where I can with the other components of the machine.

I found this ADM Phenom CPU for only 115$, it seems like a good bargain, but I know the X4 955 is much more populate then this 840. Is there any specific reason why I should stay away from this CPU?

I also plan on purchasing an ATI 6950 2G video card, will this CPU be a bottle neck?

The 840 is really an Athlon II. It has no L3 cache, while the 955 does.

I'm guessing since you'll be using a plasma you'll likely be gaming at 1080p, which means that the games are probably going to be more GPU bound rather than CPU bound. That said, the 840 doesn't have L3 cache, which seems to help in some games. Overclocking is probably out because you're running an HTPC (which should be silent), so that's not much of an issue...The 955 is only $25 more on Newegg. That's a tough call. Maybe someone else can chime in...

It's pretty much an Athlon II but it's okay for the price. It at least OC's better than the 640.

Yes ,and the tests showed a good performer.
It seems that in some aplications L3 adds latency and a performance drop.
I personally think it s a good CPU ,though the name is a little unfair.
As it s a X4 CPU it should game decent & properly.
If you don t have the money ,you are simply short of the 25 more dollars for the 955 ,get it.At high resolutions a good GPU manages a little weaker quad just fine.

Try to get a true Phenom II. More and more games are performing poorly on the Athlon II's, so just get the real thing. Try buying used if you have to.
