Cpu for AUTOCAD, only 2d

i3-2100 is best here,in my vote goes for i3-2100

wat u mean by u have to change u mb and ram? Also u need to post full info,So accordingly we could give suggestions.

Your expected budget, and psu details (make and model) would also help.

yes u are right, but it think that the mb and the ram are not so important like the cpu

Yeah further details are needed. Whichever your budget is get the fastest CPU you can afford, which in this case would be the i3. If you could afford the extra cash for an i5 (its about £40 more in the UK) I would get that. It has 4 real cores over 2 hyperthreaded which will help a bunch.

So, i'm from Croatia (the prices here are a bit higher) , my budget is around 200 euro.

How large are your ACAD files? For my newest ACAD 2D station, I use a Core i3-530 w/Intel HD Graphics. I believe that the g840 is very good for this. Even with the g530, you won't be disappointed; In 2D. The only time you may see a difference is when you, say, Explode 10,000 items at once. Make sure you select that the order doesn't matter. It's all about single thread clock speed. Get the highest clock speed you can afford. The i3-530 is 3.1 GHz, the ones you selected are 2.4 GHz, 2.8 GHz, 3.1 GHz respectively. I believe the i3-530 is about equal to the G840.

Spend extra for an i5, it will increase performance significantly, and you wouldnt have to worry about exploding like 10,000 items at once. You will also be able to learn 3D in your spare time.

hey dont buy the Caviar Green. I have a 2 tb Caviar Green myself. m trying to stop Intellipower". follow the link

I stongly disagree with Dingo07. I just went over to our 3D station. It's a Q9550 at 2.83 GHz. In 2D, there in no discernable difference in performance at all. You can learn 3D on any of these. An i5 is a waste of money in this particular case.

First of all ctbaars, the CPU is not the only factor in seeing how "fast" a computer is. I'll leave it at that...

Ctbaars - can you enlighten me and explain how having more processing power, in any situation, is a waste of money?

I've been running AutoCAD for over 20 years and on a lot of different platforms. I can tell you that you want the fastest CPU that you can find, even if it is just dual core because most of autocad only uses a single core. Unlike gaming where cpu speed sometimes doesn't improve performance, higher cpu speed will always improve the speed of autocad. The speed of the GPU really doesn't matter at all but get one that is designed for professional use so you can get proper drivers. We have had trouble with video cards that weren't appropriate. We use ATI FireGL and NVidia Quadro cards now. Currently I'm running a dual core E8500 at 3.8GHz. We have some quad core i5 machines running at 3.5GHz and they aren't any faster.

oop go with the 2120 instead, it has a 5% increase over the 2100 and costs $2 more

My files are about half mb, I know i3-530 is good, I used it at work for month and have never problems.
Thank u for the advice!

I haven't time to learn 3d and no money to waste in not needed performance. 200 euro is my upper budget limit

mine is only 500 gb, i'm haveing it from 2009, I think it will last another two years.

what about o'clocking an athlon II 250 (regor)?

that one is a old model with 5 yrs warranty i bet (have still have one with 5 yrs warranty, was warranty replaced once). Newer models have this feature. And i can tell u , m not happy with this one.
