Phenom 2 940 vs i7 920

I'm building a new system...and I am soon torn on what to get....this system will be brand new...meaning I have zero parts to start with zero!!...

I am torn between a i7 build that totals 1650 with mointor including vs amd build that total 1450 with monitor included...


of course the i7 build will perform better but you must consider what the i7 has
case
monitor
i7 920
evga mobo
2x wd black 640gb hdd
dvd burner
stock cooler
4gb pc3 ram
800w PS
ati 4830

The amd build has jus about everything the i7 build has except
aftermarket cooler
4gb ddr2 ram
730w ps
ASUS M3A79-T Deluxe mobo

I been readin that the phenom 2 is jus a upgrade cpu...not a cpu you should built a new system with...is this true or not? Is the phenom 2 worth building a new system with?

More about phenom
  1. I'd go with the i7, honestly. The Phenom II is a good CPU, and far better than AMD's prior offerings, but it is not really in the league with i7.
  2. The p2 is a major step in the right direction for amd but i7 will be better for a new build right now, also i7 uses tri channel mem so get 3 or 6 gigs instead of 4. There are plenty of people on this forum that know more than I do, but a 4830 seems like a weak video card for either setup hard to tell without knowing what you're gonna use it for
  3. if money is no object, then build an i7 system. if it is, you may want to start comparing prices. both can overclock well, both are very capable. i7 has more muscle but it comes at a cost.
  4. Well you can cut some money off the i7 build by dropping that 800W power supply, you definetly do not need all that. While this is still overkill for that system, the Corsair 750W is a great price, probably ~$60 cheaper than that 800W youve picked out.

    As far as the build itself goes, just get i7. Its worth the extra money.
  5. Yes, the i7 would be more future-proof than the P2, which will be moving to DDR3 in the next few months anyway. Besides, the i7 seems to have some "secret" gaming performance advantages in a non-GPU-limited setup (currently multi-GPU setups), and the next-gen GPUs will be out in this summer. I suspect the i7 will become the hands-down favorite for gamers in the next 6-9 months, if that is your interest.
  6. If you have the money, go i7, but you need to ditch the 4830 and get a 4850 or 4870 with the setup you have.
  7. screw that support AMD, go P2! woot woot.
  8. for the record...the 4830 is a powerful card...it can get 50fps on average in most games at 1900 b 1200....and in xf...it has the speed of a 4870.....im not a gamer...so i dnt need much in the graphics department


    but im thinkin about go i7...because i dnt wanna cry in august when my amd machine is old and rusty ALREADy...

    and im gonna get the 750 w PS

    All frm newegg...ima add some logitech 2300s...for 80 bucks...frm amazon...newegg sell them for 115..idk why..

    what you guys think?
  10. Looks like a nice build, but as previously mentioned, you'd get better performance going with a triple channel RAM kit with either 3 or 6 GB.
  11. i though about the tri channel kit...but i seen so many reviews saying that tri channel barely out performs dual channel...so my thinkin is....grab the 4gb and jus go dual channel since its only 79 dollars...and then by another 2gb stick sometime wen ddr3 prices drop...
  12. That's one way of looking at it. I suppose the dual channel is still considerably quicker than single channel. Looks like a good build then. wish I had the money for one (damn teacher's salary!)
  13. lol... do you just have money to blow or are you in a hurry? it seems as though you have a bunch of crap you really would not need and could invest in the hardcore pc components instead.
  14. yea...i took alot of crap off...like the card reader...and tv card..and jus got a basic keyboard and mouse...so that saved me like hundred bucks and i used that saving to upgrade to a xfx 4850...since they offer double lifetime warranties

    I agree %100

    If i were building today I would build a i7 and certainly would get triple channel memory...

    I see on Newegg a 3gig kit of triple channel for under 150$


    ***edit***
    My spelling sucks
  16. You could always get a Q9550 or Q9650 and some decent DDR2 with a P45. Add a 4870 or GTX 280 in and get some nice performance. Phenom 2 is an upgrade chip as you said. If you do not have an AM2+ already than you should not have a Phenom 2, period. i7 is still a little ridiculous to me, the $100-300 you can save going with a slightly less overkill CPU can net a much better GPU or monitor. All personal preference really, just stay away from Phenom 2...
  17. Yea i7 might be overkill, but how long do you see 775 mobos lasting?

    i suspect quite a while since the only choice is 775 (dual and quad cores) or a 1366 which is corei7. not everyone can afford a i7.

    True...but... How long is 1366 going to be around? Safe to say you can upgrade your processor down the road.

    If you buy a q9550 it is likely that is the last processor youll buy on a 775.

    In my opinion purchasing a system anywhere in the neighborhood of $1000 which is NOT i7 is a grave error. I can understand a person who has 600 bucks building a Q6600rig or AMD even... but if you are in the $1k area; there is only 1 choice….i7

    Im far from being wealthy… but when did 1k become such a large amount of money? I usually spend around $1800-2500 on my PC’s.
  20. 1366 will disapear before 775 im willing to bet. 1366 is looking proprietary almost, more than likely to be replaced by whatever socket i5 will be using. Id have the name of it but theyve changed it about 3 times now.
  21. i5, it runs north and south from Washington state to so cal. Hate that name. Hopefully theyll come up with something soon
  22. judging on the performance increase in i7..i dnt think there wnt be much upgrading I cnt do....when a person upgrades their PC...generally the processor is the last thing to go.... dnt see ddr3 going anywhere...sata drives...optical drives...or pci-e graphics cards...so i see it being a stable buy for 2 years at least

    This is crazy talk! crazy talk!
  24. who knows which will die first but 775 is not leaving ANYTIME soon. good luck trying.
  25. the Phenom 940 is roughly comparable to the intel Q9450 for CPU intensive tasks like rendering 3D animations.

    the i7 940 is maybe 40% faster.

    most of the time, you wouldn't notice the difference in speed. for gaming, a lot of games will be faster with the dual core 8600.

    once the price cuts hit, it's like choosing between the blonde Swedish bikini team and the redhead Swedish bikini team.

    i5 will be on a different socket, true, but 1366 isn't dying. Intel has stated that the 32nm high end parts will also use 1366, probably well after 775's demise.

    True. But I still think 1366 will become almost propritary. Rare, everybody hates it, dosent work with anything else. Sort of like Samsungs dumbass MP3 and cellphone plugs.

    I myself so wanting to know about this as well. I can't make an informed decision whether to get PII or i7.

    If the above is true, I will definitely go with Penom II. Socket 775 is not an option due to the upgrade path (I don't think Intel going to make socket 775 cpu and i5 cpu at the same time).

    Not 100% sure what the OP used his computer for. I do play game, but I don't need a 100+ fps system to play game. I do watch movies from time to time, some dvd burning but mainly the computer is used for internet browsing, email etc.
    I was thinking of getting i7 920 or wait for bit more for AM3 Phenom II, but at the moment I am leaning toward socket AM2+ PhenomII. The reasons are:
    - I can get it right now!
    - Lower cost (mobo, DDR2)
    - Future proof as I can upgrade to all future AM3 cpus says 2 years down the road.
    - I can get better GPU to compensate less powerfull CPU (if I need to).

    I think I can't think of any argument right now that will justify me to go with i7 (consider my need).
    Surely i7 is way better PII in anyway, just because I can afford it... it doesn't mean it is wise to buy it.

    Would love to hear others opinion.

    cheers,

    Ken

    I've got still a P4 on LGA775 on a "Deluxe" motherboard with chipset 915P and both DDR400+DDR2-533 support. When i bought it 4 years ago it promised to be a good buy to migrate the P4 to a new CPU and DDR2. 4 years later i learned that what you buy today won't assure the ability to upgrade CPU or RAM in 1 or 2 years time. In a year i couldn't even install a E4300 CPU and DDR2 maximum support is DDR2-600 with OC.

    Now i'm planning to "upgrade" my system (CPU+MB+RAM) and the difference between an i7-920 and Q9650 (with new prices) is about $150,00 but i7 architecture and benchmarks on multitasking ready applications is much better on i7.
    Anyway Q9650, at new price is also great and even Q9550 is a good buy but i think also i5 and i7 architecture with integrated memory controller and with integrated GPU support in the next generation in 1 year along with 32nm production will bring even more performance and another important step that will leave LGA775 platforms where my oldie P4 is nowadays.

    Games are played mostly on the graphic cards so i guess Q9650 or Q9550 (or even Dual Core cpus) are perfectly accpetable for the next years and the on-going change to keep the "FPS pace" is on the graphic cards... at least until Intel integrated direct support for GPU on the CPU as i said.

    My 2 cents...

    Well, that's an interesting idea there... but (as i already said in my latest post) i don't forget that i have still a P4 on a LGA775 motherboard with DRR400+DDR2 that can't even install a E4300... So, despite the next generation can use the same 1366 socket noone can assure now that *current* motherboards and chipsets will support 32nm CPUs, especially if Intel decides integrate GPU support directly on the CPU (the same way they did with RAM now on i7) which will require another change on motherboards and chipsets.
  32. With the new price cuts coming, I might be tempted to build a OCed Q9650 or Q9550 to tided me over the next 3 yrs and then go with an upgrade.

    New pricing from Intel:
    Q9650 $530 -> $316
    Q9550 $316 -> $266

    Should start showing up shortly (Might put further bind on AMD pricings).
    It's getting close to "buying a car that can go 220 mph while Most (not all) roads are limited to 65 mph.
  33. i think Phenom II much overclockable now ..
    AMD Phenom II, 3.9GHz Air-Cooled, 6.3GHz Liquid, Chicago :)
  34. That video is old news.
  35. Bad grammer and for Phenom 2 to be able to compete with a Q9400/Q9550 or above it has to be able to hit 4.2 Ghz on air atleast, because the Q9400/Q9550 are faster clock for clock and can hit 3.8/4.0Ghz respectively. That is the problem.
  36. It goes like this. Ask yourself what you use your PC for. Can you justify the cost of the i7 cpu, ram and MB for your every day use. Just take a look at the benchmarks and your questions should be answered. If you are a gamer like myself who only does the regular stuff then the i7 is a big waste of money. There is no point in buying hardware that will not yeild you results you actually use.

    Very good point Chief. Everyone so concerned about a socket future and who really keeps a motherboard beyond 2-3 years? The price of that 9650 blind sided me. I didn't expect a price that cheap for that CPU for a good while yet.
    By that same token, who cares if the 1366 gets retired? You don't think the i7 can compete for 2-3 years? I do.
    While there are a ton of AM2 boards out there right now that are affordable, chances are good that the AM3 boards may be the tipping point that makes the P2's scream like a banshee. Then you are left to spend more money to take advantage of the power you already have.

    IMHO...take your pick. you CANT lose right now. All are great deals and it's win/win/win.

    Pretty much.
  43. It just getting better with the price cut.
  44. Tailor your CPU-mobo-GPU to your uses, what use is a i7 system to a person that uses it for e-mail, surfing and gaming? As Retiredchief said we're getting to a point where people are recommending a 220mph car to folks that never drive over 65.......... and btw put a 1,200w power supply in it.
  45. Thats why most of the PCs I build are using E2180s @ 3.0Ghz and are getting the desktop performance of i7 as long as the multi tasking is not insane, there is no heavy gaming, or the CPU is encoding/converting stuff... $50-$70 CPU...
  46. So kirvinb what did you end up deciding?
  47. intel > amd

    Agreed. Even though I have an i7 and love it, the cheap duo or quad is a far better way to go for most. I have the i7 because I multitask heavily, sometimes having 3 windows of firefox, Windows Media player, 2 other assorted programs, and Matlab open simultaneously. I also use the computer for SolidWorks and Matlab quite extensively, not to mention gaming. This is far from a standard environment though - most people would be well served by an overclocked duo or low end quad, and it will be cheaper both in initial cost and electric bill too.
  49. Totally agree cjl if I did something that actually justified an i7 CPU I would buy it right now... kind of wish I did do something to justify it...
