I wonder, if I should pick an Intel Core i7 920, or an AMD Phenom II X4 965. What I will be using my computer primarly for is gaming,
Price doesn't really matter
. Now I want to know which one of these that will give the highest performance/overclock, and I want to overclock 'em A LOT ! I will be using watercooling,
AND NO FANBOYS!!!!!!!!!!!!!!!!!!!!! I THINK AMD AND INTEL BOTH MAKE GOOD CPUs SO NO BULLSHIT LIKE "INTEL MAKE BETTER QUALITY CPUs" OR "AMD SUCK BALLZ" OR "INTEL IS BUTTER WHILE AMD IS MARGARINE(hehe I hate margarine ) OR SOMETHING SIMILIAR!!!!!! INTEL'S WEBSITE IS MAYBE MORE SEXEYYY BUT THEY DON'T MAKE COOL DRIVER UPDATES LIKE AMD!

It depends. If you want to go with a single powerful GPU (as many people does) then there's really no difference since you will not be able to have a bottleneck on the CPU with a single card (at last not in this generation and I think neither the one to come).

If you want to go with CF/SLI with two powerful cards (275/4870 or better) or 3-SLI/CF-X then you'll experience a great bottleneck on the CPU with a Phenom. This naturally becomes more evident at high resolutions since at lower resolutions the FPS are too high (in almost all titles) for the eye to recognize it, but it's there nonetheless.

Spending more for Core i7 is only justified with an high-end SLI or Crossfire setup elsewhere you will notice no difference whatsoever in gaming. With an high-end SLI/CF setup however the difference between the two CPUs is substantial.

Articles you want to read:

For SLI/CF performance difference a system with i7 offers: (not compared with a Phenom II but the results are the same)

For a comparision between a PhenomII rig and an i7 one at the same price range (note that the i7 system in the article is based on a MicroATX board, so it doesn't reach the full performance of and ATX one for various reasons, one being the PCI-E lanes speed on that MicroATX board):

well as a workhorse, the i7 is a tough act to beat. if you are gamer-centric, then go with the Phenom 2. i am not going by review sites, benchmark scores or personal bias. i have both and the P2 has a cleaner, smoother feel to it playing games. the best combination i have tried so far was a P2 955 with a GTX 295. adding a second one did not go so well. it could do it but it required pushing the hardware beyond what i was comfortable with for 24/7 usage.

However a GTX 295 in a Phenom II gives a bottleneck on the CPU being about two 275 in SLI. If you play on resolutions at or above 1080p you will notice the difference the bottleneck does; it is there also on lower resolutions but usually (apart some titles as Crysis) the fps, either if bottlenecked, are too high for the eye to discern it.

If you read the first article I mentioned you will see this clearly in benchmarks.

As for the smoother feeling I cannot understand what do you intend. FPS is what makes a game smooth or not, and FPS in a SLI system are greater on an i7 system, so there's no way you can perceive playing on a PhenomII with a 295 as "smoother" than doing the same with an i7. On a single-GPU system, however, there's no difference and smoothness relies on the GPU you have (and RAM etc.).

If money is not a problem then get the most expensive i7 (i7 975) with 4 64GB Intel SSD X25-E in RAID-0. Top it off with 2 or 3 EVGA GTX 295.
 



Gaming.... Single, or Multi GPU?

Single? Doesn't matter, really: Get what you like. Or what's on sale. Or the one in the green box 'cos that no good ex girlfriend has blue eyes, so you hate blue. Whatever. With a single card, it won't matter.


If you're planning on SLI/Crossfiring (or Tri/Quad) in order to drive a large resolution monitor, then you may want to weight your decision towards the i7. But don't take my word for it - GURU 3D tested it for us

if i get a normal liquid cooling system the maximum over clock is 3.8? or better (with i7 920)
and maximum over clock for P II 965 is 3.6 or better?

f i get a coolermaster v10 or v8 cooling system the maximum over clock is 3.8? or better (with i7 920)
and maximum over clock for P II 965 is 3.6 or better?

I don't know the coolermaster v10 performance first hand, so I don't know for sure, but with a good air cooler the i7 920 with the D0 stepping can reach about 4.0 ghz. There are some people that are able to put it at 4.1-4.2 ghz on air, but it naturally depends on the processor you have (everyone behave differently) and naturally how good you are at OC. The usual max OC of the i7 920 D0 is 3.8-4.0 GHZ on air.

As for the PII usual OC varies between 3.6-3.7 GHZ, but there are people that put it at 3.8 GHZ if not a little more.

Go for either.

And the Phenom II doesn't bottleneck with 2 or 3 video cards like one of the posters is attempting to claim.

Awhile back there was one review where the reviewer admitted he had driver problems but he posted results anyway. People have been quoting the incorrect conclusions from that review as being "proof" of this "fact" since that time. In several later reviews it has been shown to not be true.

This makes many people wonder why some people still cling to that incorrect conclusion.
 
if you don't really have a tight budget (ie >$1000) go for the i7, it handles programs that are cpu heavy better (ie video encoding)

though if you have a tight budget (<$1000) go for the phenom II, though i would make sure you get an AM3 board and DDR3 memory, you never know how long AMD is going to keep that DDR2 controller around

Dead on. The P2 doesnt show any signs on bottleneck unless you are dealing with quad or tri SLI. I dont know where that crap is coming from.
OP, both will do 3.8 on air pretty easy without the expense of liquid cooling. My 920 D0 will do 4 on air with right around 1.27 volts. The P2 has much better temps though to be honest. It isnt just CPU temp you have to watch but the voltage regulators on X58 boards can get very hot.

hey plz help me..
m also confused in between two cpu's i want a system which is best for runing softwares like maya, after effects, photoshop, n many multimedia softwares so which one is best n any one will suggest a motherboard for it it would b very grateful... :)
 
If the pricing difference between an i7-920 system and PII X4 965 system doesn't bother you... I'd vote for the i7. Over all, the i7 is the stronger performer. The PII X4 965 isn't a crappy processor by any means, however from a sheer performance stand point, it's the lesser of the two processors.

If you don't mind spending the money, want the best gaming system, and don't want to upgrade as soon down the road, then i7 is the best choice regardless of which i7 CPU you go with.

Here's a recent comparison of the two @ stock speeds (i7 = 2.66Ghz, PII X4 965 = 3.4Ghz)
http://www.overclock3d.net/reviews.php?/cpu_mainboard/amd_vs_intel_-_the_gaming_sweetspot/1

Interesting how the i7 at lower clock speeds, matches the 965. It's a 740Mhz difference in clock speed, but the Intel chip still performs as well (even better) in tests. This is why I say to go i7.

+1 i7 (or even i5) if you want to pay $200+ on a CPU.

If your budget asks for under $200 on the CPU, go AMD. Phenom II keeps up in gaming on nearly any GPU setup with i7, although i7 (or i5) will keep you good into the future.

@neal4u, for nearly anything other than gaming i7 is going to be superior.

ok den now i can go wid i7 n now plz suggest me a best board for it as well m livin in delhi so which motherboard i should buy for intel n for amd too.. n a graphic card :)
