hi everyone !!

i'm building a htpc(which will also double as a gaming pc)... i'm planning on buying the components sometime in decemeber before christmas

for the cpu i was wondering whether i should go for the intel core i5 or the amd phenom ii x3 720 ??

i know the performance of core i5 is brilliant... but the question is do i need it ?? will x3 720 suffice ??

this is keeping in mind i'll use it both as a htpc and a powerful gaming rig..

More about : core 720

i saw some where that amd were planning to release amd phenom II x3 740.... so now the competition is between core i5 and x3 740 !!

i5 is much better, but x3 is cheaper, your call.

Since you're using at as a powerful gaming rig, the i5 is the only way to go. Recent reviews have the i5 overclocking to 4Ghz+, making it an insanely powerful chip for the price. HTPC duties will be a walk in the park for it.

The AMD chip is nice, but with the ATI 5870's out you'll want all the CPU you can get. SLI 285's or crossfired 5870's can even bottleneck a 3.6Ghz i7 965. Bear in mind though that with all this powerful hardware in your pc you can't expect it to be particularly quiet.

thanks guys...actually a hd 5870 is a bit outta my budget... 5850 would be what i can probably afford...

and i thought gaming pc's require more of graphics power and cpur's don't actually matter much

get the 720, at high resolutions with anti aliasing etc, the gcards will bottle, not the cpu

Which is generally true and an X3 740 won't be bad with a 5850, recent games and video cards seem to overpower dual cores but a 3rd core is a big step up, more so than a 4rd core is compared to triple cores.

Either one will be a very good choice.

not really... competition is between real products that you can buy.


If you have the money, get the i5.

If you want to save money, I think you'll still be very happy with the x3.

The 5850 is a good choice, it looks to be a powerful card. While it is true that GPU matters more than CPU when it comes to gaming, recent GPU's are so powerful that you simply cannot expect a CPU like the X3 740 to cut it in 2+ years time if you're wanting to play games at high settings - AKA powerful gaming rig. The i5 has much more grunt and will deal better with an SLI or crossfire setup.

xaira - if you look at reviews with crossfired 5870's they can bottleneck a 3.6Ghz i7 965. Guru3D has a review where 2x 5870's are bottle-necked in World at War by the i7. Not a huge concern, but it is an indication of things to come.

Suggesting that the fourth core is quite insignificant ??

oh !! meaning it'd be future proof for some time.... atleast compared to an x3 ??

Future proofing is a myth, 2 years from now the i5 will also have been demoted to "mid-range" that's the way it goes with hardware (the Q6600 was the best CPU of January 2007, to give you an idea) and about that 4rd core? Yes, it's quit insignificant compared to the 3rd core.

should i take the call based on my budget ?? or simply go for core i5 because its better

If you can spare the money then get the i5, if you're tight on budget then get the X3.

how much is the price difference approximately expected to be, between the core i5 and x3 740..sometime in december ??

In both cases you'll want 4GB of DDR3 memory, so no differences there, a good AM3 motherboard can be had for $80, an i5 motherboard will cost you $100, the i5 750 CPU costs $200 now, and the X3 720 costs $120.

to be honest i5 beats 720 easlily
for games it really depends on the GPU but if you also use it for other purposes i5 is I think the best choice
especially with turbo speed ofr single threaded apps

future proofing is not a myth, the i5 is already a mid range cpu, the best future proofing sockets are 1136 and am3, get the 720/740, unless you plan to do some heavy video transcoding with that htpc, ur better off with the 720

Sure, Intel's PR department says so, then it must be true...

I can imagine Nvidia wanting to call the GTX 285 their "mid-range" card, just because they have a GTX 295.

To gamers the i5 and PII are just as much "high-end" as the i7.

There will be future CPU's for LGA 1156 as well as LGA 1366 and AM3.
It sure looks like Intel is going to bring almost all their new CPU's to the LGA 1156 socket, the LGA 1366 will only get a 6-core in the near future which will only be useful to software developers and scientists as there aren't even plans for games that utilize six cores, not even Supreme Commander 2, so it'll be years before the first 6-threaded games will appear and the people who will pay a lot for the extra 5fps the 6-core gives will also be the people who will at the same time throw away their (then 4/5 years) old X58 board for something newer and shinier, and you can bet your ass Intel will have invented a whole new socket by then for the second generation 6-cores...

As other have said, it depending on your budget. if your tight on money, get x3. If not then i5.

Some of the thing help in your decision.

First: If your multi-tasking the more core the better. Also include background programs that may start up at anytime like anti virus, This will reduce the chances of game slowing down due to multiple stuff trying to running on already used cores.

Second: Budget.

third: Socket future. Look to see if there going to be more cpus on the socket your looking into for the future. ((if possible) and if upgrading cpu in the future is a priority.)

Forth: general use.

Hope this helps.

Hey thanks everyone... i guess i'll go with the core i5... price difference seems pretty less... atleast that's the decision for now... unless someone comes up with any new processors between $130 and $150

well the phenom 2 x4 945 is lke $150 and the 955 BE is 180 USD.
