Hello everyone,

Before I begin with the below discussion, I'd like to make it clear I am in no way an AMD nor an Intel fanboy and I'm just trying to be neutral and going for the items that best suit my needs and money. Now to begin...

I was researching the new intel i5 750/i7 860 & the Phenom II X6 1055T.
*Comparison of the X6 & i5 750
*Comparison of the X6 & i7 860

Prices for my area, since I'm located in Australia: X6 $235, i5 750 $235, i7 860 $330.

I've found that the X6 is better during out of game performance, which would help me when I'm doing 3D animation/rendering/w.e due to the multi-threading. However I also game, which is where the X6 lacks power in. Until somewhere in the future, when the X6 is able to deliver all it's multi-threading performance in games when they accept the hexa core's capabilities, intel's range is going to out perform.

So for future proofing, maybe the best way to go is to get an X6, especially since Intel uses almost a new motherboard for every new processor range they create whereas AMD focuses on a single chipset for several years at a time making it compatible with previous boards.

Now the real question on this CPU is this:
*If I were to turn off the X6's turbo core and overclock it to 3.5ghz, would it be reasonable performance as compared to an i5 750 during gaming use?
*Also, if I were to overclock to 3.5ghz, would I be able to do it with a 250 FBS with untouched RAM & voltage settings? Would I really need to touch the multiplier? (based on this)
*Finally, what would be the the best motherboard for this overclock? (preferably a gigabyte). I'm still looking for a motherboard and was thinking I could try to find the best one that would mold around the overclocking capabilities.

Even though the URL in *2 claims they used stock CPU coolers, there's a fireplace in my room I use during winter (PC will be at the bottom of the ground, though. Less heat) so I'll be using a better cpu cooler than stock, haven't chosen which yet though.

For the graphics card, I'm going to use this $240 quite heavily factory overclocked ASUS 460GTX 1gb (not worth buying a 5770, 5830 or 5850 for the comparison. 5870 is heavily over priced for $500).

I should do fine by myself finding memory, cpu fan, PSU & anything else. Looking at an end result of $1,100 for the comp, not incl. monitor or any other peripherals.

Cheers.

For gaming performance, just go look at Phenom 965 benches, gaming wise the perform clock for clock identically. the fact is with Thubans you can hit 3.8Ghz with the stock cooler w/o much effort, so 3.5Ghz, especially with a better cooler can be done by just raising the Base clock, which cooler do yo plan on using?

Board wise, Anything 870/770 and up would be fine, depends on your selection and price really.

GPU wise, whats your prices? Id get a normal 460 and OC it yourself, but the ASUS cooler is great.

Finally, where would you be buying from? The prices don't quite look like MSY.

I'm currently using a mix of http://pccasegear.com prices and the cheapest few selections from http://www.staticice.com.au/.

If what you claim is true, that the cpu may hit 3.8ghz on stock coolers, that doesn't really tell me if it can be done without touching anything else except the FSB. I assume the multiplier would need to be tuned from 16x to 14x, I'm new to overclocking and the lesser the better. I don't really see processors needing more than 3.0ghz~3.5ghz these days, I'd like it to last a while. Doesn't overclocking it too much lessen it's life span?

Not to sound like an A-, but it would be nice to know what people had to tune in order to achieve these results. I've been looking at this, but doesn't clarify to me what the minimum tuning is required to achieve such results. I'm assuming some people are just guessing some silly numbers and such here and there to produce such results, if it seems stable they stay with it, rather than trying to find the most stable specs they can use to replicate the same performance.

The reason I chose the ASUS factory OC'd card is because it has a higher bus width & higher shader frequency. The memory & engine overclocks are pretty standard elsewhere I suppose. For the price, it's not that bad going with the few extras.

Price wise: $1,100 for the entire computer (Case, mobo, psu, ram, gpu, cpu). I was looking at this $235 x6 cpu, $240 gpu, $140 ram, <$200 mobo, <$100 case, <$150 psu. That's $1,065 (or a little less), gives me some extra for a better cpu fan & part of my peripherals & <$200 monitor. $100 mouse, $75 keyboard, $80 headphones/mic.

Checking the p65 now...
Edit: Pretty good gaming performance, and I also assume it'll be slightly higher on the x6 further yet. Very competitive to the i5 & i7 offerings I listed above, even more so if I were to go about 3.5ghz OC. Any higher is still IMO, too high.

3.5Ghz on stock is definitely doable, heres a screen shot for example.
The fact that some boards default the X6s to 1.4v also makes things much easier.

As the impact on the CPU's lifespan, as you keep temps under 60, you'll be fine. It is going to be barely noticeable as you're going to switch CPUs far before that.

On the 460, all 1GB models have the wider 256-bit bus, and Shader OC is as easy as dragging a slider up in Precision/Afterburner.he ASUS card is great though, so its not a bad choice.

On the boards, heres some nice choices:
(The worst board you'd want, still decent.)

(To note, you wont be able to SLI on either of these boards. AMD SLI boards in general isn't something I would recommend.)

Thanks

I think I may wait for the bulldozer though actually =/

After all, the x6 1055T may not last 5~6years under that overclock even with default voltage and stable cooling I spose.

I never really cared about SLI or CF, just going to be using 1 monitor at a time at highest reso (or maybe two, one main and the other tuned to desktop only and not games for chatting, if possible).
