So I'm in the market for a new system. My existing system is old and needs more RAM and at this point it'd take a new motherboard to do that so at this point I may as well spend a bit more and get into a more modern system. So I've arranged a four way cage match for your enjoyment.

I am a gamer but typically always at lowest settings and solid playable framerates are the only really important thing here rather than niggly FPS counting. I'm a constant multi-takser, always ALWAYS playing things in windows and running something else on my second monitor. I'm not even vaguely interested in changing that; my new chip MUST be able to handle that because a step back at all in this area would be a major downgrade even if I can get a few extra FPS.

Without further ado - The contenders

The Dual Core Wonder - Pentium G3258

This was my immediate instinct for building a cheap system. My computer only seldom uses multi-threaded anything and this chip has serious bang for the buck in single threaded workloads. It's cheap it's got OC overhead and I already have a solid aftermarket cooler to save on that. Clearly a strong contender.

The Bulldozer - AMD FX-4300

It's a bulldozer chip but let's not hold that against it. It's trading raw performance for multiple cores. I'm replacing a four core chip, so it'd be nice to get at least that in my new chip too. Like I said, multitasking matters to me and things are seldom bottlenecked by my CPU at the moment so perhaps this is a better choice my actual day to day life.

The other guy - Athlon X4 860K.

I actually forgot this chip exists. The FM2 chips just never struck me as being all that exciting. Anyway this is another 4 cored chip with decent clock speeds and some overclocking room too. I have absolutely no idea how this stacks up against Bulldozer but this chip is in my price range and the idea of having an Athlon branded chip again makes me feel warm and fuzzy.

The Wildcard - My existing Core 2 Quad q8200.

Why am I putting it up in this comparison? Because honestly I've gotten by fine with this chip for years. It's only very recently that I've felt it's holding me back what so ever. I'm definitely over-due an upgrade (particularly from DDR2) but this chip is the baseline for comparison.

The new chips have to justify their cost against my Q8200 and at least make an argument that I'll see a tangible improvement in my day to day life. If they can't do that then I'll most likely be aiming for a more expensive build at a later date.

I leave the rest up to you guys.

FIGHT!
 
Dual Cores are on their way out for gaming, as newer titles are running into problems running well (or at all in some cases) with the Pentium, even with a heavy overclock. The Pentium is really only a good option if you are either using it as a placeholder CPU until you can afford an i5 or i7 or you're only interested in older games, indie titles, and Free to Play MOBAs and/or older MMOs. Newer big budget triple-A titles really need a quad core now, and the Athlon is the best out of the ones listed. The big drawback with the Athlon is it's the best CPU available for its platform, if you need more CPU horsepower, you will need a new motherboard as well (possibly new RAM as DDR4 becomes the new standard over the next couple of years).

So in today's world is single threaded power less important? I was always lead to believe that Intel's lead in single threaded power meant they smoked AMD chips with more cores. Has that changed particularly? And how does the Athlon perform in single threaded stuff? I wonder because a couple of Unity games I've been keen to try are reportedly very CPU bound and don't multi-thread well.

Everything is a trade off of course but it's weird to me that for a while people raved about the Pentium as the best budget gaming chip around.‎
 
Single threaded performance is still important, particularly for games running older engines, but dual cores aren't cutting it anymore for the latest titles. It's why if you're going to go Intel, getting an i3 is the absolute minimum (hyperthreading lets the OS see it as a quad core chip and it does help a fair bit) with the i5 being the recommended CPU. If you can't afford either, you're either stuck going with AMD or saving up more money until you can afford a decent Intel CPU.

The Athlon will lose out by a large margin in single threaded performance, but will do better in newer titles that need the higher core count. The Pentium looked pretty attractive when it first launched last year, but games that came out in late 2014 eg. Far Cry 4 and Dragon Age Inquisition, and most of the high profile releases this year have really shown the Pentium's limitations. It's a great little CPU if you want to dabble in overclocking without risking expensive hardware or if you're only interested in pre-2014 titles, but it can't keep up in the current environment.

If you really need the single threaded performance, your best option is probably to save up a bit more money and go for an i3. It will offer slightly better single threaded performance than the stock Pentium and do a fair bit better in newer games than the Pentium thanks to hyperthreading.
 
Not less important but the fact is both the 860k & fx4300 are both 'fast enough' for the majority of users.
The Pentium is a waste of money in this day & age - its one saving grace is the possibility of future upgrading to an i5/i7 without having to purchase a new motherboard - that's all.

The performance between the 4300 & 860k is incredibly similar (roughly a 50% increase over your current c2q CPU).

The fm2+ (860k) chipset offers cheaper decent quality motherboards than am3+ ($40-$50 or so for a good quality a68 board) , it has non up grad ability though - its the fastest CPU you'll ever get on that socket.

Personally I'd look at a little extra & try & up to the 6300 if at all possible , in the UK at least the price difference between the 4300/6300 is only around 15%.

You're definitely right about cheaper motherboards on FM2. Ten seconds on amazon brought up some nice A88X boards with 4 Dimms and a bunch of spare SATA ports in the £30 to £40 range which is always nice to see. Maybe I can't put it a new chip in the board but I can easily add more RAM, more HDDS as I need the. My old board has 2 SATA ports and that drives me nuts!
 
Just be careful with boards regarding the 860k

Check the CPU compatibility lists on manufacturers websites & make sure its supported on the 1st revision bios.
A lot of boards may require bios updates to run it & without an older compatible chip you can't do this !!
Be aware of that , its caught many a budget of builder out.
