You're not going to "future proof" yourself with a current quad.
When Duals were new - I bought 2 AMD FX55's - the BEST unicore my money could buy.
Those two systems are still running very strong today.
And we all know how old the FX55 is.
If I had put my money into a DUAL at that time - it would be garbage today.
You should, IMO, pump all your cash into the best DUAL your money can buy. You'll be much happier in the long run - when people (today) who are buying those brand-new quads are shopping for a NEW quad - while your DUAL is still running strong.
That's my $0.02 - after 15 years of building and buying PCs - I made the same mistakes everyone else is making - but a long time ago.
Listen to what I'm spouting - and you'll be a happier gamer.
Think Quad's going to do your gaming good - well - you'll be buying a new CPU in a year or two when you get sick of bad performance.
( Really - you should take a look - "bigger numbers" isn't always better. There's underlying reasons here that lead to a complex explanation - lol - but just trust me on this one. Remember Athlon / P4 - where these "weak" Athlons with low MHZ were burning P4's that were "twice as fast" number-wise? Exactly. Dual > Quad right now. Especially for games. If you want your 50 copies of firefox to run nice with Photoshop and a few MS Office apps - Quad's for you. If you game - Dual's for you. )
Intel Core2 = best current CPU out there.
Sadly.
I COULDN'T HAVE SAID IT BETTER MYSELF.
IMO That's an end-all to the debate. Go see the CPU Perfoamance for yourself. lol.
No need to listen to any IT professionals lol. We don't have pictures.
If you notice - the only things that are getting good scores on quads -
- Professional imaging programs designed for workstations (multicore systems)
- Experimental programs
- Benchmarks
All of which are not really anything that's going to do any of us any good.

You know - now that I look even more at these benchmarks ...
I'm wondering why I've even considered an Intel.
:\ Hmm ...
For the $100.00 Amd X2 6000+ to get THAT close to a $1000.00 Core2 Emergency Edition -lol- is pathetic.
The only result with a big difference ... was a benchmark. Applications are what matter IMO - not benchmarks.
I dunno. All this new "intel hype" may be just that.

... I think I'll withdraw my statement that Intel's starting to get good.
AMD just got ... distracted.
They just got a huge influx of cash thanks to my bros out there in UAE/Dubai.
I'm expecting great things from AMD in the next couple years.
Yep...Intel has the best quads right now from my point of view. I'm using a AMD Dual core right now but I'm planning to upgrade.
Might think about going to an X2 6400+

Hmm ... Interesting.
I've been good with my hardware since I bought smart the last time I upgraded. I haven't been paying much attention to the hardware market in the meantime.
This sounds like ...
Intel's P4 toying with benchmarks and designing their CPUs to perform like champs -
on benchmarks.

Very close.

But if you look at the benchmarks - there's a big spread on most of them for the Intel - with Intel on top.
I dunno. With the prices the way they are - if you put enough power into that CPU and make it cost 2x as much to produce, well there's no wonder it's going to get that extra performance boost. This is going to be vanilla P4 all over again.
Whatever. AMD's been sticking it to Intel for a while now. Give AMD a year.
Intel's going down (again.)
