Need some help deciding, i3, i5, or i7.

post #1 of 13
Thread Starter 
So I am rebuilding my computer that I have been using for a long time. You can see from my sig, it is an Athlon X2 5000+ and integrated graphics. I managed to acquire a Gigabyte Z68 board, so the decision for which camp I am going with and which socket has already been made. Now I have to decide between three processors:

i3-2120T - 2.6 GHz 35W - 134$
i5-2405S - 2.5 GHz 65W - 219$
i7-2600S - 2.8 GHz 65W - 309$

This computer is in my room and cooled by an H60 and 3 PWM fans. It is important to me that the build be quiet enough to sleep with, so I have limited myself to 65w and below processors. I'll be using a passive cooled Radeon 6670 for graphics - though this hasn't been decided and I am up for suggestions on a passive cooled card - and a passive cooled Seasonic PSU.

Honestly, I have had no real problems with an Athlon X2, but I have been wanting to play Starcraft 2 for a while and perhaps do some PS2 emulation. Mainly, though, I just use the computer for writing and watching some movies or listening to music. I'd like to fold with something more than a 5 year old dual core processor though, which is why the i7 is even on the list. Money isn't really an issue so much as whether it is worth me spending it, which is why I need some advice. I find it hard to justify spending 310$ on an i7 knowing that I probably have no reason at all to do so, despite the fact that the money is there should I deem it necessary to get one. The debate between the i3 and i5 is more over power consumption and a quieter computer.

So a few main questions:
Is the i3 and a 6670 good enough to play Starcraft 2?
Is there a noticeable difference in gaming on an i5 vs an i3?
Is there a massive advantage between folding on an i5 vs and i7?
Anything else I should consider?

An i3 and 6670 can play Starcraft quite well. I wouldn't imagine there's a large difference between an i3 and i5 when gaming seeing as most games depend more on raw GPU power than a good CPU. Can't comment on folding - isn't that a GPU thing?

I wouldn't bother with an i7, go with an i3 or i5. i5 to be safe. Also if you can buy the 2500K.

With only one GPU, I'd say i3. I have one, and I love it.

Edit: noticed you fold... An i7 should be able to do -bigadv, which does give a boost in PPD.

Not for long. I think starting next month -bigadv goes to 16+ cores.

EDIT: Nevermind, already happened back in January. Same idea applies.

Welp, in that case, I definitely recommend the i3.

go with the I3 2100 its 65w and under load on air i max 40-45c in F@H & IBT using a CM Hyper TX3

I3 2100 $124.99 @ newegg

Head to the market and put up a wanted thread for an i3 21xx. I have gotten 2 i3's from there a 2120 and a 2100. One for 90 and the other for 85$.

My choice should be obvious i3. tongue.gif

If you need even lower powwr just undervolt a regular chip. I saw someone here get a 2100 to 0.975v rock solid stable. Was pulling 48watts with prime 95 running all out.

Add in sales tax and gas cost to get to the store and back. 99$ cpu quickly becomes 120-125$.

Head to the ocn marketplace.
