I'm thinking of upgrading a little and i'm looking at my processor. It's an AMD 64 3000+ Venice 1.8Ghz. I'm talking to this guy that has an AMD X2 3800+ (not sure what version) I like to do several things at a time (which would be the X2) but i like when my games load quick. I would get it for about 130$ Canadian. Is it worth the jump?

WesternDigital 80Gig SATA
Antec TrueControl 2.0 550

If you multi-task or run software/games that can take advantage of the dual core, it *might* be worth upgrading. If not, stick with what you have & overclock it. You should have no problem hitting 2.25GHz (9 x 250MHz) with your 3000+.
TigerDirect Canada has the X2 3800+ Manchester (OEM) for just $100:

Your games will not take advantage of dual core if those games aren't designed for dual cores. It's only been recently that games are starting to be designed to take advantage of dual cores.
Now if you do a lot of photo editing, video editing and play the most recent games that can take advantage of dual core technology, then it is well worth getting a dual core.

Without getting into details, I do have problems hitting anything over 2.2Ghz Jam. The problem doesn't lie in the settings, it lies between the monitor and the chair.

I'd spring for an X2 4400+ it has a larger L2 cache and that helps when your dealing with large amounts of data.

Multi-core is the direction CPUs have been headed for a while now since single-core CPUs can't be made any faster than they already are. So to get more computational capacity out a CPU you simply have to think in terms of multi-core solutions. Therefore, I honestly would not recommend getting another single core. Furthermore, applications are going to have to increasingly become optimized for these line CPUs because of the single-core speed barrier mentioned earlier whether their code programmers like it or not.
http://www.newegg.com/Product/Produ...BTW, don't let the 1.8GHz top speed on the Denmark fool ya, your 3000+ is no match for it at all & those puppies are easily overclocked. For example if you look at the feedbacks - from the link, you'll see people easily running the CPU at 2.7-2.8GHz without having to raise the stock voltage on the CPU. That could mean easily squeezing another 50% (or more) speed out of the CPU for free & as I imagine not very many people will object to that type of bonus.

And that's due to the fact that Opterons are designed more durable because they are server processors.

Hmmmm, between my monitor & chair is the keyboard & mouse...lol.

"Your games will not take advantage of dual core if those games aren't designed for dual cores. It's only been recently that games are starting to be designed to take advantage of dual cores."
I am sorry, but this is wrong. It is true that one core will process more information than the other, but 25% or more of the actual processing will be moved over to the second core, even if the games were designed without dual core in mind, and I don't care what the white papers and the web reviews say. It has nothing to do with the way games or benchmarks were designed, it has to do with the daul-core architecture itself and how it chooses to prioritize the thread processing. You can see it for yourself in Windows Task Manager if you want to.
Case in point: Benchmarks I run like AquaMark or 3dMark2001 or Commanche4 show significant boosts in dual-core cpu's, even before the processors are overclocked. I upgraded from an A64 3000+ to an X2 4400+ and at stock 2.2 ghz stock gained up to 15% OVER my OVERCLOCKED 3000+, which ran at 2350 mhz. I overclock my 4400+ to 2937 mhz and now record between 20% and 60% over the oc'd 3000+ scores, depending on the benchmark of course.
Will you see a difference in your games if you upgrade to X2? Don't expect an X2 to make up the difference between GeForce 6 and 7/8, especially in newer games, but HELL YES, you will see a remarkable improvement. 3800+ is an excellent overclocker, all the X2's and dual-core Opty's are. And as cheap as they are right now, you won't regret it.
Peace and Out, Tripper.

So let me get this straight. You’re saying that top sites like Tom Hardware and what they say about how games won't take advantage of dual cores that don't support dual cores are wrong, but yet you are claiming that your method is right just because you do a few tests? Yeah sorry I think I’m going to believe the guys that spend 10's of thousands of dollars on reviewing products then I am someone that runs a few test.
Furthermore you're missing the point of how dual core games work and how they can take full advantage of dual cores cpu’s with simultaneous load rendering.

Yeah, they got it wrong; they spend tens of thousands of dollars to prove themselves right, but the fact is you can prioritize how each processor handles the load; it may not necessarily improve the performance, much like the dual-core gpu's which run games and such not designed for them either, but those duties are split to some degree between the two cores and there will, or should, be at the least a minor boost.

Ok well again your test vs 3 diff other top websites say diff, so yeah i'm going to tend to beleive what they say. I think they would know more about what they are talking about then some personal user running a few test. My statement stands.
