I'd say Core(1) is probably about even with the Athlon X2s, so you'll probably see a significant boost by waiting. 20-30%? It will also be 64 bit, so I'd wait if you are going to keep it for years. If you upgrade every year or two, though, I'd just get something now. There's always something coming out in a few months that will be faster.
from hardocp, i dont know if this is relevant or not, since gaming performance is GPU bound not CPU bound, but i leave the judgement to you guys/gals

Interesting article. Thanks for posting.***
What about this one:

Focussed on multimedia.Furthermore there's a comparizon with a AMD FX-63:-)
P4 Prescot generates a lot of heat. To cool down a CPU, you need a good heatsink, good thermal paste & good fan. When the CPU gets at 60 celsion, the fan try to do faster to compensate... The fan going faster will create a lot of noise... The noise annoys me...
Core 2 Duo uses less power and therefore produce less heat (According to all reviews at least)... Having a CPU that generate less heat will allow me to have fan going slower... You see where I am going?
This review and others I've seen, compare Core 2 with P4 or AMD. But what about the difference between Core 2 and Core? I'm mostly interested because I'm about to upgrade my laptop and I'm wondering if it's better to wait for Merom or whether there's not a significant difference between Core and Core 2 that would make the wait worthwhile. I'm sure it'll be better, of course, but does it represent a significant jump or just a speed bump?
But what about the difference between Core 2 and Core?
The Core 2 has shared L2 cache.The Core has unshared L2 cache.
Which means one single core can consume up to 100% L2 cache (Core 2) when only one core is used.

Also, i suppose that when a process is migrated from one core to another, this process can reuse directly the shared cache instead of refilling the cache of its core.
That is a great thing.

No, the Core architecure uses separate L2 caches (2x 1MB and 2x 2MB), one specifically for each core. It's similar to putting two normal CPUs together into one chip package. Depending on the CPU, they even have to go across the FSB to access data in the other core's L2.
The Core 2 architecture uses a single, shared, 2 MB or 4 MB L2 cache. Each core can access the full 2 or 4 MB. The cores dynamically assign the L2 cache as needed to eachother. And they can access data that the other core put in the cache.
Big difference.
So HardOCP is saying compared to an AMD this is not that big of a performance boost...not suprising really. I cant wait for the next gen AMDs to come out based on 65 nm...and quad cores...with HT 3.0. Supposedly it is an FP monster that new architecture. Time will tell. Nice reviews but a bit disappointing this Core 2 cpu. Considering all the numbers that were released early on how they were 40% faster than FX processors in virtually every benchmark, this is rather lukewarm.
What I am interested in is how the processor from INtel will scale and how it would handle having more cores added to the die.
HardOCP is intentionally choosing to GPU-limit their game benchmarks to demonstrate that there is little substantive difference in practice for the gamer. Even NetBurst processors will show little difference if you start playing at 1600x1200 with a single GPU. If you start looking at the overall benchmarks you will see that the Core 2 is clearly offering higher performance per clock with lower power consumption. If what you'll be doing is GPU-bound then it doesn't matter what you have performance-wise. Compared to Intel's performance with NetBurst, though this is quite an improvement and given the intended pricing makes Intel's offerings very competitive. That's now, and not at the end of 2007 or 2008. With the reports of air overclocking around the 4GHz mark, there is clearly much room for the processor to scale. The biggest problem with the processor until next year will be availability.
A sad day for home users, gamers, and hobbyists, perhaps. Or, it could just mean cheaper Athlon64s for everyone.
Definitely a sad day for AMD-based laptop makers, but then, AMD has never really had a strong laptop CPU.
But, until Intel scraps their shared-bus chipset/memory layout, they will remain second choice for all multi-processor server setups. There's still nothing in Intel's lineup that can even match a lowly Opteron 2xx setup using single-core CPUs.
