i5 Processor 661 3.33GHz w/ 4MB Cache, HD Graphics A good buy? - Page 2

post #11 of 19
core i5 - 661 is a Clarkdale. I recently upgraded from an overclocked dual-core i3 530 (Clarkdale) to overclocked dual-core Pentium G3258 (Haswell). Clarkdale has a slow memory controller and it won't perform well in some demanding multiplayer games (especially mmo's). In one mmo which I often play, my frame rate increased from approx 20 (measured in a particular location) to approx 45 (measured in the same location).

I did an interesting experiment with my core i3 530 @ 4GHz.
Disabled hyperthreading and then tried to play the Dying Light demo (on steam).
With hyperthreading enabled, Dying Light on the core i3 530 is smooth and playable.
With hyperthreading disabled, Dying Light on the core i3 530 a slideshow and frequently freezes and is 100% unplayable.
On Pentium G3258 @ 4.4 GHz, Dying Light is smooth and playable, except every 5-10 minutes, and sometimes in a big fight, the game will freeze for a few seconds.

My point is ... don't buy a Clarkdale for gaming. The single threaded performance is much too weak.
I bought my G3258 for $70-$75 and my MSI H81M-P33 for $45 and I'm quite happy with both, even though some games don't run well on the G3258.

Here's a memory comparison of Clarkdale core i3 @ 4GHz vs Pentium G3258 @ 4.4 GHz
Even though the ram is the same 2x2GB DDR3, the Haswell Pentium memory controller is so much faster.

That is why I was recommending 860K. Its a good CPU for games since it has 4 cores.

However, legacy motherboard are often very expensive (especially the one you can overclock)... I tried to grab a nice Z77 board but they are selling for 200+$. Even mediocre P55 boards are selling for 100+$. My advise would be to check the market place here and on other forums like Hardforum, etc. There is also a sub reddit where people trade their hardware. If I was shopping, I would first check for a good motherboard or a combo. CPU are very easy to find so this is the last thing I would shop for.

cool thanks for the advice!

If you're shopping for used CPU's, see if you can find a 2500K and motherboard. The Sandy Bridge i5's are still very viable, and a lot of people are putting them on the secondary market now because they've moved on to X99 or Skylake and DDR4 platforms. That would be way faster than a 661.

The only problem with a Pentium G3258 is that you're wanting to play the latest titles, and a lot of them either don't run well on a non-HT dual core, or refuse to run at all without a hack. Overclocking the 3258 to the moon helps, but there are still times you need more than two threads.

The AMD 860K is also an option, as others have mentioned, but you have to overclock it to get anywhere near the performance of a stock 2500K. You can get them for $70 sometimes, but they typically need a high-end A88X motherboard to reach maximum overclocks. At 4.5 GHz, it has a performance range between the i5-2320 and an i5-3570, depending on the program.

I second this. If you're looking for cheap, go with an i5 2500k or the Athlon recommendation. I can't say much about the performance of the Athlon, but a 2500k @ 4.4GHz should be able to handle anything thrown at it without needing superior cooling. My buddy has been holding onto his 2500k for quite some time now at stock and its been holding up just fine at 1080p.

If you want to save a bit more, then you can also look into Intel ES processors. You can find plenty of those for much cheaper than the consumer counterpart while being able to use consumer boards. (Only some can OC though)

if he wants to go cheap he should be looking at a g4400 skylake with a cheap asrock mobo.... then at least he can always upgrade to a i5 6600k if he ever need or want too. dual core skylake is as good if not better than a quad i7 920.

for that price you should be able to get a i7 860/xeon or i5 2500k, either one would be a lot better
