And still on the i5-3570k Vs. FX8350 battle, being the latter an octacore processor does that necessarily translate into much more solid and better actual multitasking performance? Also, since I'm planning on building this new rig with at least 8 gigs of DDR3-1866 memory, a dedicated graphics card (NVIDIA GTX650Ti) with two monitors having lots of videos/programs/processes going on all at once, do you think I'll benefit more from having the AMD extra cores or Intel HD4000 IGP graphics on the system?
Any suggestions and opinions are welcome here!
I guess it depends on what you mean by multi-tasking performance. I'm sure there's a scenario in which the AMD octacore
will perform better. If you wanna batch-apply hardcore Photoshop filters to high-res pictures, encode an AVI into a MP4, play a game and record footage of it all at the same time? Yeah, the octacore might win. (Of course, your system will slow to a crawl, but the octacore might crawl faster in that scenario.)
But the i5 will run
just the game better than the octacore can. If we're talking light multi-tasking like running a many-tabbed browser on a secondary monitor, maybe occasionally checking email, and running an MP3 player in the background while you play your game -- you know, standard stuff, then the i5 will still fly.
Again, not all threads, and not all cores, are created equal. Not all programs are heavily multi-threaded. Many programs you might be apt to use for what we call "multi-tasking" effectively don't demand CPU resources constantly or even concurrently with other programs you'd be apt to use.
There will always be give-and-take in discussions like this one, but I feel that the discussion is too focused on core count at the expense of everything else.
Right now, the i5 is unambiguously superior for most any gamer who does light computing on the side (either at the same time or separately). The alternative in our little comparison does better at certain tasks than the i5, but they're not tasks that the average gamer values very highly.
The FX
might prove to be
slightly more future proof in the next 2-3 years. Future proofing is generally a fruitless endeavor, though, and this topic illustrates why: we just don't know exactly what will happen. By the time any of this stuff we're talking about matters,
both processors will probably be well aged and generally undesirable. The fact that the FX
might be slightly
less undesirable later isn't a terribly compelling argument given that it's less
desirable now.
All of that said, the FX is not a
bad gaming CPU. It's just not as good as the i5 -- as of now and for the foreseeable future, which may or may not encapsulate the timeframe you have in mind for your particular rig.
It's also worth noting that your particular graphics card (650 Ti) will likely bottleneck
both CPUs in this discussion; if you have yet to buy any of the parts, I would suggest downgrading from a 3570k (either to a locked i5 or to a cheaper AMD CPU) to put more money into your GPU subsystem. If your primary interest is game performance, it makes no sense to buy the best gaming CPU on the market (or near enough), only to pair it with a low-end video card. Personally, I'd need to be in the market for
at least a 650 Ti
Boost (Note the "Boost," and yes, that silly little word is important) or an HD 7850 before I even thought about installing a 3570k -- and even then I'd probably end up taking money away from the CPU to upgrade to an HD 7870.
To get a little more detailed, a 650 Ti costs somewhere around
$130 on newegg right now. An i5 3570k
costs about $230. If you downgrade that 3570k to, say, an
i5 3350p, then you'd save about $50.
That $50 increases your GPU budget to ~$180, which buys you a 2GB GTX 650 Ti Boost. If we assume that you would have
also bought a ~$30 aftermarket cooler with the unlocked processor (but not with the locked one), then your GPU budget balloons to ~$210, which buys you
a GTX 660, or gets you within spitting distance of an HD 7870.
A build with 3350P + GTX 660 or HD 7870 will absolutely smoke a build with a 3570k + 650 Ti in most games.
