Need a new CPU for 30K(without harddisk and gfx)

[darth_sithus]

1. What is the purpose of the computer? What all applications and games are you going to run?
Ans: Matlab, Lotus Domino Server(For testing), Lotus Domino Designer, Visual Studio 2010, Simulation algorithms that might run for days in Matlab/scilab. Games like BF3, Rage, MW3, Crysis 2 and other future titles for atleast 2 years.

2. What is your overall budget? If you can extend a bit for a more balanced configuration, then mention this too.
Ans: Wont mind spending upto 35k but would prefer if budget stays within 30k

3. Planning to overclock?
Ans: Yes but only normal ocing with stock cooler.

4. Which Operating System are you planning to use?
Ans: Windows 7 Home Premium/Windows 8/Ubuntu

5. How much hard drive space is needed?
Ans: Not needing HDD now but need mobo with atleast 2 Sata 6gbps ports for future upgrade)

6. Do you want to buy a monitor? If yes, please mention which screen size and resolution do you want. If you already have a monitor and want to reuse it, again mention the size and resolution of monitor you have.
Ans: No. I already have a FHD 22" monitor.

7. Which components you DON'T want to buy or which components you already have and plan on reusing?
Ans: GFX Card: 9800GTX. HDD: Western digital 1TB 3 gbps+external 1tb connected to firewire. Monitor: Viewsonic 22" LCD. Keyboard

8. When are you planning to buy the system?
Ans: within a week

9. Have you ever built a desktop before or will this be done by an assembler?
Ans: I will build it myself

10. Where do you live? Are you buying locally? Are you open to buying stuff from online shops if you don't get locally?
Ans:Mumbai. Prefer to buy from Lamingon Road

11. Anything else which you would like to say?
Ans: Will be purchasing a powerful gfx card in 2-3 months, so please comment if any good cards are releasing in the near future(Budget: 30k)
Both me and y brother will be using the PC and he wants pc to run network simulation algorithms written by him which run for days. So multitasking and high uptime is of prime importance.
Mouse:My old Logitech mx518 is dying on me. please suggest a mouse worthy to succeed the 518. budget will be what i can spare after buying the cpu.

So in compendium, this is what I need:
CPU+Motherboard+Ram+PSU+Cabinet (30-35k)
Mouse(Spare budget)

AMD FX 8120 @ 9.5k
Gigabyte GA-990XA-UD3 @ 9.5k
G-skill RipjawsX 2x4 GB 1600 MHz DDR3 @ 3.4k
Corsair TX750V2 @ 7k
Corsair carbide 400R @ 5k
Total ~ 35k
For cabinet you can also go for NZXT Source elite 210 @ 2.5k

AMD FX 8120 @ 9.5k
Gigabyte GA-990XA-UD3 @ 9.5k
G-skill RipjawsX 2x4 GB 1600 MHz DDR3 @ 3.4k
Corsair TX750V2 @ 7k
Corsair carbide 400R @ 5k
Total ~ 35k
For cabinet you can also go for NZXT Source elite 210 @ 2.5k

Kind of overkill components. Here is a balanced list

AMD FX8120 - 10k
Gigabyte GA970A-UD3 - 6.8K
G-skill RipjawsX 2x4 GB 1600 MHz DDR3 - 3.4k
Corsair 650TX - 6.1k
Corsair Carbide 300R - 3.8k
Total ~ 30100

>A Corsair 650TX will suffice your needs when you buy a good graphics card like GTX670 or HD7950 later. GTX 670 is a better option at around 26-28k.

>Corsair 300R or 400R should be minimun in your case as you are getting a high end GPU and also you plan to overclock your system, so good airflow does matter in your case, and that too pretty heavily.

>An AMD Bulldozer series will help you achieve good performance with those simulation programs.

>A 970 chipset based Motherboard is enough for your requirements. 990FX makes sense only if you intend to SLI or Crossfire in future. Here's an insight into it -

990fx - x16,x16,x4 (dual x16 for Crossfire/SLI)
990x - x16,x8,x4 (x8 x8 for Crossfire/SLI)
970 - x16,x4 (x16 x4 for Crossfire/SLI)

Crossfire or SLI on two 16x slots will obviously give you better results than on x16 and x8. So thats what 990FX is meant for.

>For Mouse, have a look at Logitech G500, Razer Deathadder, or the cheap and best, Logitech G400 (This mouse was the descendant of MX518, so you will feel like home while using it) . You have additional 5k left in your budget if you tend to go with my config, you can buy any good mouse with that.

FX 8120 will consume more power when OCed, so tx750v2 would be better.

@darth_sithus

Config I
Processor:AMD FX 8150 @ 12k;
Motherboard:Gigabyte GA-970A-UD3 @6.6k
RAM:Gskill RipjawsX 4GBx2 @3k
Cabinet:Corsair Carbide 400R @4.5k
PSU:Corsair HX650 @7k or corsair tx750v2 @7k
CPU cooler:CM hyper 212 evo @2.1k
TOTAL=35.2k

Corsair HX650 is a modular psu,would be better for cable management.Hyper 212 evo would help in overclocking

Config II
Processor:Intel i5 2500k @12.5k
Motherboard:Asrock z77 extreme4 @10k
RAM:Gskill RipjawsX 4GBx2 @3k
Cabinet:Corsair Carbide 400R @4.5k
PSU:Seasonic S12-II-620 @5k
Total=35k

i5 2500k would give good performance both in single threaded and
multi-threaded tasks.AMD FX 8150 is very good at multi-threaded performance.

I think fx8150 is a better choice over gx8150.
Clocks of fx8120 are too low,0.5GHz(base clock) slower than FX8150.
Even phenom II 1090t is a better choice because of higher IPC.

 

[darth_sithus]

Thanks for the reply guys. I should have mentioned that I am not going for a OC right away. I might try to milk the proccy at stock speeds before I try to overclock(that is 7-8 months down the line).

Is the bulldozer good enough at stock speed? I have read that it has to be overclocked to ~4.5ghz before it could even start to match the 2500k? The applications I use are heavily threaded and I certainly like an affordable octacore, but it at the same time, IVB and SNB are far more superior to bulldozer in core-core performance.
So far I have only tested my applications on server class hardware at office and the machine could handle it without breaking a sweat.
I don't have any idea how they are going to perform on a desktop processor
BTW taking the rest of configuration in consideration, here are my narrowed choices:

Processor: AMD FX 8150 / Intel i5 2500k
Motherboard: Gigabyte GA-970A-UD3 @6.6k / ? (I dont need SLi/crossfire. just suggest a board capable of handling a single powerful gfx)
RAM: Gskill RipjawsX 4GBx2
Cabinet: Corsair Carbide 400R(Read good reviews about this one)
PSU:Corsair HX650

CPU Cooler: Deepcool Iceblade Pro (Or better, for later purchase. please dont consider this in my current budget)

So it has finally boiled down to: AMD FX 8150 or Intel i5 2500k. Which one should I go for?

 

[desiJATT]

You are mentioning this again that your usage will be heavily multithreaded. That narrows it down to AMD Bulldozer. Per core performance wise SNB and IVB are better, its true. But we are talking about applications using more than 4 cores, so intel is out of the way.

Go for FX8120 instead of 8150 as the difference between the two is very less but the price diff is higher.

Motherboard is just OK for your requirements.

 

[vkl]

Yeah, agree with desiJATT.
The difference between the prices of fx8120 and fx8150 should not be that much.

If OP is going for a BD based processor then fx8150 is a better option according to me as in some scenarios it is noticeably faster than fx8120.In many multithreaded tasks fx8150 keeps up with i5 2500k and beats it in some but fx8120 rarely matches i5 2500k.Fx8120 gets beaten by phenom processors more often than fx8150 does.
Moreover in games at 900p and high settings fx8150 is significantly faster than fx8120.At FHD the gap is lesser though.

An i5 2500k would be a nice option too.
In multithreaded scenario it is very close between i5 2500k and fx8150.
In tasks like 3d modelling and rendering fx8150 beats i5 2500k handily because
in tasks like that the number of cores matters a lot.
It is way more power efficient and also overclocking it would pay more dividends.
In gaming i5 2500k has the advantage though it is negligible at 1080p.

@op
Add an ssd later to the config.It will make your system much responsive and faster.

 

[darth_sithus]

I am going for AMD FX 8150 and Gigabyte GA-970A-UD3.


My Final config:

AMD FX 8150 ~12.5k
Gigabyte GA-970A-UD3 ~6.5k
Gskill RipjawsX 2x4 GB 3.4k
Corsair HX650 7k
NZXT Source elite 210 2.5k (Had to go for this due to budget constraints)

Total: ~32K

With the spare budget I will go for Razer Death Adder or logitech G500 depending on how much I save

 

[darth_sithus]

Sorry for the bump.

I purchased the rig and now I have assembled it.

Had a little difficulty while mounting the CPU but else everything went perfect

Just wanted to confirm one thing. Will the CPU be a bottleneck in high cpu utilizing games like SC2 and Skyrim at 720P and 1080P?(Currently playing BF3 at 720P without any lag)

If so, will overclocking remove the bottleneck?

 

[Myth]

The fx8150 wont bottleneck the gtx9800

 

[avinandan012]

^ err it is July,2012 era of Keplar

 

[darth_sithus]

No not the 9800gtx. I was talking about the AMD 7xxxx/NVidia 6xx series as I would be upgrading to a high end GPU in near future.
