    Hi!

    I bought a ASRock Z77 Extreme4 mobo and some Samsung 30nm ram but no CPU for my new rig.
    Is HT in an i7 3770 Ivy Bridge worth the extra 100 bucks over a i5 3570 or i5 3550 CPU without HT?
    I´d use the rig for gaming and my day to day stuff.

    unless time is money aka you video encode for a living , i5 2500k is the way to go :)

    I know I probably don't need it but I usually go with CPU's that have HT but that is me cause I like to have it just in case but whatever is in your budget is what you should get. If you can locate a cheap 2600K then thats what I would get but if 2500K suits your need then you should be set :)

    Why 2500k 2600k over an Ivy Bridge?

    When they introduced HT on the pentium 4 people couldnt stop laughing about it. Its just marketing.

    More threads are always welcomed, but for me i say if i can get more cores (Intel not AMD cores) the better and i it comes with hyper threading even better, so if there were an i7 with 6 cores but no threads i would go for that over an i7 with 4 cores 8 threads.

    If you are asking this question then you should get the i5.

    Really now? Check out the different between a 2500K and 2600K in WCG and come back with your result :rolleyes:

    Cheaper, performs the same, has more of a temp tolerance with overclocking.

    @Brandon

    Not everyone crunches. Name a few other things that can utilize the extra 4 threads. I can't think of anything else other than trans/encoding.

    That only applies to overclockers though, if you are not overclocking then IVB is slightly better.

    Ok? Then compare pricing between an i5 2500k and i5 3450 3550?

    2500k: 3.3Ghz/3.7Ghz Turbo
    i5 3450: 3.1Ghz/3.5Ghz Turbo
    i5 3550: 3.3Ghz/3.7Ghz Turbo

    Going by current prices on the 'Egg. The premium for the unlocked multi would be worth it.

    EDIT:

    Then if you look up to 4c/8t cpu's you have the i7 3820, which right now is $20 cheaper than it's 1155 counterparts. Granted the boards are touch more expensive but an even better cpu all-around. I don't care who you are, Ivy right now to me is reminiscent of Bulldozer, but in aspect with it's extra heat at lower end clocks.

    A slightly related question: HT is good with heavy virtualization yes?

    Egg prices 3550 and 2500K the same, personally I would get the 2500K for my usual day to day activities since that I will be doing some overclocking, but if you are not the 3550 is slightly better. The advantage of 2500K only shows when you overclock, if not then the 3550 is ever so slightly faster. The small amount of temp increase at stock doesn't really translate to higher power draws. Try to look from the perspective of a regular tech user not a power user, and you will get my point.

    2011 is actually a good idea at current prices if you need all those threads.

    Not when you account for that extra $10 promo card. What I am saying is this: for those regular users that don't mind doing a few small tweaks; 4.4Ghz > 4.1Ghz. Both clocks can be obtained at stock voltages. I understand what you're telling me, I know exactly what you're saying.

    @Frick

    Yes.

    I completely understand what you mean too, but other users prefer to keep their stuff at stock. I met a person unfortunate enough to get an unstable overclock but did not get picked up by the usual stress tests. A few days worth of simulations down the drain, which is why I understand some people rather keep things at stock.

    Eeek. That's a very very unfortunate case. Might have been a dud cpu, I would had rma'd it.

    question is, should one rather invest the extra cost of i7 in a better videocard which would give more fps improvement if gaming is the main purpose.

    ^^What this man said was true in P4 days. I remember doing extensive testing and in the best possible circumstances you could expect a 15% improvement. In worst case situations you could get a 5% reduction in performance. (Poor thread scheduling, optimisation, cache clutter, etc.). Net result was on average about 3-5% gain on multi-threaded applications. NOT WORTH IT. It really was marketing spin and a small OC or BSEL mod would be a much better way of getting higher performance.

    ^^What this man said is true today. New Intel processors will give you a gain of 70% in best possible circumstances and a loss of 5% in worst case. On average you will get 30-40% gain on multithreaded applications. DEFINITELY WORTH IT. All said and done, if you only use your PC for gaming and don't really use multi-threaded applications or run concurrent applications, then a non-HT is fine if it saves you budget for more RAM or better GPU

    this answer is simple if you are an enthusiast, then yes the i7 is way better... better for folding, crunching, multi tasking, anything that utilizes all threads the i7 will be better in.
