Will a Pentium G860 bottleneck this?

As some of you know, I plan to build a new rig this year to replace my Pentium 4 primary machine with a modern Pentium G860. I plan to make it a beast for gaming as well, and I wanna know - will a G860 bottleneck the current 7870, and the next gen 8870? If so, how much performance will be lost? Should I put in a 7770/8770? Any answers will be appreciated.

Planned board to use with it btw: MSI H61M-P31

BALANCE IS KEY
meaning dont cheap out on cpu hoping the gpu will carry it, give your system the tools it needs to do its job, mabye look into qa bundle deal on ebay or similar, you want a quad core, the only dually worth anything nowdays is the i3 and tomorows different again, you see?

See here's the thing - I'm not cheaping out on the CPU, I WANT to get a Pentium - it's replacing my Pentium 4 system so I wanna continue the Pentium name with my system. And actually, a Core i3 is really just a Pentium with Hyper Threading & some new technology.
EDIT: Also, I'm a strong believer that the quad core CPU won't be necessary until everything is heavily multithreaded - I believe a dual core, so long as the architecture is new, can keep up to a quad core in regular tasks.

When I hear the word "Pentium", this immediately comes to my mind. I know it doesn't exactly answer your question. What about the HD 7850/8850? ;)

Well I don't plan to play Far Cry 3, but more so like Counter Strike Global Offensive, Fallout New Vegas, Bioshock, maybe Crysis 1 & 2, Max Payne 3- at least medium settings you know? Nothing too demanding.

There is nothing wrong with a Pentium G for gaming it is still a good CPU and won't bottleneck most GPU epseically not low end gaming cards like a 7770 or 650/650Ti. If anything I would go with a more powerful video card.

I hear so many people talk about how many programs are threaded to take advantage of multiple cores and that is not even the point at all. Who only does one thing at a time on their computers... exactly, no one. Many people run a game, a browser with a bunch of tabs some with flash, a media player, a downloading program and handfulls of other programs simultaniously. A quad is going to have a massive advantage in system performance while multi tasking. Seriously Payturr just spend the money and get a decent i5.

Thanks rds, thats just what I needed to hear :)  And again, to CMI, I understand the whole CPU industry & whats best for who & what not, and I recommend CPUs to people daily, I just want a system based around the Pentium just so I can keep the name alive, because its a successor system to my Pentium 4 rig. I like i5s and all but I want a tribute machine to my P4 rig!

When you have money to throw around, it doesn't really matter - besides, the Pentium G isn't too shabby for what it is! Pretty strong CPU actually, considering its just an i3 with no working HT.

Do you actually use a pentium 4 machine all these years for gaming.

Put this into perspective just as a guess.

video encoding on 3ghz p4 = 24 hours. 100%cpu usage games 10fps with lets say a 6770. encoding takes 150w to run
video encoding on 3ghz core 2 duo= 3 hours 80% cpu usage games 60fps with lets say 6770 encoding takes 70w to run
video encoding on 3ghz i5 dual core mobile- 30 minutes 40% cpu usage games 60fps with lets say 6770. encoding takes 60w to run
video encoding on 3ghz i7 quad mobile= 10 minutes 20% cpu usage games 60fps with lets say 6770. encoding takes 80w to run


These are the figures you are likely to see.

No, I haven't been using a P4 system for gaming - no AGP slot so. On top of that, the new system is gonna be the G860, not the P4. And I love my P4.

Note w is watts for power connsumption. Less is better.

Yea so your point is? He didn't mention anything about about video editing or anything else that would CPU intensive he wants to play games.

payturr I mean also as your main computer or what other computer do you have.

Trust me though realistically a core i3 will be like 5-10x faster then your p4 at a lot of things. pentium g860 will bottleneck the graphics card you want. You need a minimum of an i3 to have a chance with a 7850 and an i5 to be safe. pentium g860 will have same framerates with a 7770 as with a 7850 as it will be cpu bottlenecked.

I know a P4 isn't the best but all I do on the system is webbrowse, besides this I have a junky A4 laptop which is okay for gaming. There's nothing wrong with the Pentium G - I don't wanna pair it with like a 690, I just wanna know if I could put it with like a 7870/8870 with no bottlenecks.

The i3 only has the slight strength over the Pentium because of hyper threading. When you put that aside, essentially they're the same CPU.

Look at this showing i3 beating pentium or be it closely. There are more intensive games out there though:
http://www.anandtech.com/show/4524/the-sandy-bridge-pen...


Lol the I3 should beat out the a lower ranked Pentium G just like an I5 should beat out a lower ranked I3 and Pentium G. Also in most of those games it is only a few FPS difference between the Pentium G ad I3.



This is the biggest gap in the games benchmarked at a 5.2 FPS difference. Still that is one game and it isn't that bad



.3 percent difference really that is barely worth mentioning



This is another gap but still 4.5 isn't that bad



Again only a 1.7 FPS difference.

For games no. The I3 has the edge because it is a stronger CPU. Games don't make use of hyperthreading and it doesn't really increase performance. If anything it can give up to a 2% performance penelty in games For CPU intensive programs like video encoding the I3's hyperthreading will help and give a further edge over the Pentium.

Well I meant for gaming its a very slight strength. I don't do video encoding so I'll never know the differences. :p  I was just staying that once you put hyper threading aside its really the same CPU - same cache, almost the same clockspeed, stuff like that.

Hey op i know you want a pentium although what you think about the 965 black edition when overclocked its perfomance would out perfom the pentium with no problems at all and it a quad core. http://www.newegg.com/Product/Product.aspx?Item=N82E168... and its only like 20dollars more imo if your looking to save money thats a MUCH better choice buts its your money

Unless you plan to upgrade the pentium to a i5 then i would say get the intel board

Yes it is close but not the same. If you take hyperthreading out and look at just thecore power than yes it it close but not the same. The I3 has a stronger, faster CPU core.

The 965BE is a nice processor, but its too old for my taste - its age shows its poor efficiency compared to a modern processor, and on top of that, it bottlenecks most GPUs you put it with unless you get a 4/4.2GHz overclock out of it. I plan to go Pentium because, again, I'm replacing my Pentium 4 machine with a new one and I want to keep the Pentium name going - the G860 is a great processor for the price, and obviously can do laps around my P4, plus it's not too shabby for my intentions (gaming & this forum).

Well thats true but rember a 4.2ghz 965 is MUCH Faster and its a quad core. but your heart is set. :p

Well compared to a modern Pentium its not faster everywhere, just some areas. Kinda do wish AMD still made CPUs like the Phenom II though.

rds I did say there are more cpu intensive games. These games are to basic but for games like battlefield 3, dirt showdown, gta 4 etc i3 will destroy pentium g860. Hyperthreading on i3 dual core makes a big difference for games. pentium g860 is more core 2 duo speed even though it is sandy bridge it lacks a lot of memory bandwidth compared to i3.


First of all you are underestimating the power of a moden dual core Intel CPU. You may have to turn down the settings from ultra to high but I have no problem with that given the Pentium is a budget CPU. Next you are compleatly wrong about hyperthreading. Hyperthreading does NOT help gaming performance that has been proven in benchmarks. If anything it can hurt gaming performance with up to a 2% performance penelty. Thats why no one recommends an I7 if all a person is doing is gaming. You are paying 100 dollars more for cache and hyperthreading two things games dont make use of.
