Does anyone know of any reviews of say x1900xts and 7900gtxs with lower end cpus like a 3200+ or 3800+
Any reviews of HIGH end GPUs with LOW end CPUS

Akshayt is an expert on CPU limitation, ask him. You could run an X1900XT-X with a 386 and any problems with performance would mean the card "is crap," at least that's his reasoning behind his X1900XT-X underperforming with a 3200+ behind it.
Seriously though; I don't know where to find benchmarks like those, but a 3700+ would be my personal limit with recent graphics cards. When I gradually OCed my 3400+ to 3700+ I saw considerable increases in performance with my X1800XT all the way up to 3800+, but as I went up from there the performance increase was marginal at best.

Unfortunately it is very hard to find any benchmarks like what you're talking about. Benchmarks tend to test hardware in combination with all cutting edge parts as opposed to what people are actually likely to have in their systems.

I see on Toms cpu charts that a 3800+ is = to a pent 4 670 prescott at 3.8 in games. So your saying you would need a pent 4 at 3.6 to 3.8 to get the full potential from a x1950xtx or 7900gtx? Thanks in advance.

The X2 3800 is a dual 2ghz core setup. On a dual core enabled game, you will be fine.
You need 2.4ghz on an A64 to get full advantage out of todays top end accelerators in a game not built for dualcore.
So even the 2.4ghz single core 3800+ could possibly bottleneck your GPU. But not enough to worry about.
This article did not have C2D available at the time of writing.
The single core 3800+ makes a lot of sense, since you are a gamer. Dualcore is good, but not the prime pick for gaming at this point unless you get the 4600+ or higher.
Or overclock the X2 3800+ to 2.4ghz+.
I'd suggest either the 4600+ X2 or single core 3800+. C2D works too, but might be a pricier investment and wont give you much gain over a 2.4ghz+ A64 in your games.
On a sidenote- what about online gaming? Does a dual core CPU help with the "feel" and framerate when playing a fps online? My single core now provides great gaming performance but when I'm on a server you can see the frame rate drop(and feel the slowdown) as the more people join the server. Someone on the forums has said a dualie helps with this. Any feedback on this?
You will get some hearsay on this subject, but theres really too many variables involved without doing specific tests on your machine in this scenario.
Could just need the choke adjusted on the connection, could be a saturated server, could be your CPU, could be a low FSB limitation if it was an older processor or mobo, could be merely temporary net conditions or placebo effect, could be the GPU.
I'd write off most "simple answers" to this question as a wives tale.
The best simple answer is that of course a faster CPU and PC setup in general is going to be smoother and more consistent in online gaming.
So yeah, I'm sure a dual core does help. Is this the de facto fix to this issue? No. Sorry.
It only means it helped, somewhat, on that particular persons rig.. and thats assuming it was not placebo effect or wishful thinking because he blew his wad on a dualcore.
I'm not taking a stance either way, just stating the facts for you. I can say that the fact it was a :thumbsup: DUAL CORE :thumbsup: :disgust: wont help anymore than a blistering fast single core, such as an overclocked 3ghz A64 or 5ghz C2S beyond extremely rare situations like the Quake4 enhancements.
Even there, no online play is going to be subdued if you are running a 5ghz C2S, by any means. Dual-core isnt magic, and if you read my link from my post above you'll see there are still plenty of legacy app issues with the technology in gaming.
Thanks for the input. I flip flop on whether to go with a dual core every other week or so...Wish we could wave the magic wand and speed up software development.
IMO, your rig is at a very high level of performance as is. It is doubtful you will see a framerate increase in modern games with faster cpu, except for maybe Quake4 and Farcry (which I believe is run off the quake engine but I could be wrong). Your GPU is what is "limiting" your performance, and you would have to spend at least $250, more like $300, to see a real increase, imo. I would wait till DX10. It is also highly unlikely that you could hit your current overlclock with an X2, meaning your GAMING performance could DROP slightly. However, reaching > 2.4ghz on an X2 is very likely, meaning that you won't suffer much in gaming performance, if at all, and your multitasking performance will go up (in general I find most "general" multitasking on an AMD64 with 1gb of ram pretty fast as it is).
Basically, with your setup and even my setup I wouldn't upgrade until DX10 cards come along. I might make the conroe jump but thats only because the family needs another computer.

Just for the record (and fyi) FarCry is Crytek engine, not quake(actually Doom3) engine
edit: I also wish more reviewers would review GPUs with low-end CPUs, tool. I've got a 7900GS massively OCed with a stock A64 3500+, and every review I see features significantly faster CPUs (X2 4800s, p4 3.8ghz, and now C2D).
No problem, and so do I.
I want dualcore to. But what has been discussed in this thread about dualcore gaming are the facts of the matter I cant deny.
4600+ or higher X2 is what I'm shooting for. But a single core 2.4ghz+ is just as good for taking advantage of any GPU out there today, while not having the DC caveats I linked to in this thread (such as dealing with odd FPS caps ect).
For me, overclocking my 3200+ that I bought years ago now is something that I cant let go of till it dies or 2.4ghz Athlons arent the magic number anymore for unchaining GPUs.
I mean of course dualcore kicks ass for making a rig smoother overall, but that high ghz on the A64 is still necessary to take advantage of singlecore built games, which is such a massive majority that I cant deny that either, so for me a 3800+ X2 is useless without an overclock to 2.4.
I'd rather just drop the extra pennies on the 4600+ and not have all the hassle and sometimes strange side effects of OCing on my rig.. takes a while to get things completely straightened out sometimes when overclocking
Remember, an X2 3800+ runs 2 cores @ 2 GHz each. 2 GHz is the speed of a 3200+. For multithread-ehanced games, the X2 will be great; for older games which aren't enhanced for multiple CPU's (which is most of them), the X2 would benefit from some overclocking.
The beautiful thing about the X2 3800+ is that it's a gem of an overclocker. 2.4 GHz should be a piece of cake, no matter the revision (more voltage might be reqired for older chips), but the newer ones go to 2.7 + .
So, with a little bit of overclocking, that X2 3800+ will be more than enough, and provide for an excellent gaming experience.
I agree 100%. My parent's had a o/c'ed Semperon system that was damaged in an electrical storm recently. I built them a new system with a 3700+ that does 2.65Ghz on stock voltage. I am using my 3800X2 @ 2.65Ghz as well, although I needed 1.45V, which isn't a huge increase.
