did a search on "firing" as well as "scaling" and didn't find anything. figured i would post because i thought this article was really a good article. the main parts that were interesting were the benchmarks at 1600x1200 @ 4aa 16af. seems that at this resolution(about the res at what most high end gamers play) the difference between an a64 3000 and having an a64 fx57 is really nothing.

so for those gamers thinking of buying a higher end 300-450 dollar cpu (3500, 3700, or 4000) and then a midrange gpu (6800 series) you may want to look at just picking up a 150 dollar a64 3000 and then using what you saved on your cpu to pick up a 7800. you will get more bang for your buck at the higher resolutions. (i have always said a gpu is more important than a cpu. this article just is a nice confirmation)

Wow thats really surprising... I remember seeing some extremely CPU limited benchmarks not too long ago, what gives? This is the total opposite of what I read the last time someone did a large scale CPU scaling compairison.

I guess it makes sense though... crank up the resolution and AA and the video card will need more power. There really isnt anything you can crank up to stress your CPU more though (except for MAYBE some physics settings in 1 or 2 games).

well this is average fps.... too abd they didn't show the minimum fps which wouldindicate a better playable experiences....

if someone sees an article on CPU scaling for 7800 SLI, i would be interested

This is intresting.
so now i feel, X2 4400+ or 7800GT? i have money for one of 'em.

Wow thats really surprising... I remember seeing some extremely CPU limited benchmarks not too long ago, what gives? What gives? 1024x768. This isn't really surprizing to me. Doom 3 maxxed out with 4x AA at 1280x1024 floats around the 60fps range most of the time, but my cpu usage is only at a max of about 80%, usually a bit lower. I've notice this in other things as well (Luna barely touches 50% cpu utilization, and with a 2500XP).

People who said that 7800GTXes were useless with current cpus needed to notch up the image quality.

easy decision. if your main concern is multitasking, rendering, or encoding choose the x2. however if all you use your fast computer for is gaming then choose the 7800 gtx. either way you will be happy.

also be on the lookout for the 350-400 dollar x2 3800. it should be out soon and may be a better buy than paying 550-600 for the 4400.

Yes, but i think the 4400+ is a special series.
it has more L2 cache then the 4200+ or the 4600+
strange

Any info on the clock speed/l2 cache etc of this 3800+.

The thing is i wanted to get a faster cpu long back (wen i got this ), 3500+ was fastest then over here, now 3700+ and 4000+ have come. it will take a while for x2 to launch here.

EDIT: Yes, but i think the 4400+ is a special series.

Yes, thats the reason i want 4400+

rohit x2 3800 cores are 2ghz 512kb cache chip. (manchester core) my guess is that a x2 4000 (would be a 2ghz 1mb cache chip) will come out as well but this hasn't been announced. the x2 3800s are arriving this week. http://www.theinquirer.net/?article=24933

as to the extra cache and speed on the x2 4400 you are correct that it will be faster and that the extra cache does help in games. however the gains will be nowhere near the extra 50 percent price increase that the x2 4400 has over the x2 3800 (350-400 to 550-600 is about a 50 percent price increase) and as you can see at high resolutions this difference is negligible.

Ah, thanx, now, i will go with 4000+ (if it exists and releases), or this 3800+.
but it will take more than a month for it to come here. my country is slower wen it comes to tech. the p4 6xx series launched 2 weeks back. so you can get the picture of how long till i get the x2.

I love my 4000+ and won't be changing it til AMD is producing a 3.0 gig plus chip, which the way things are going, won't be long. I am dreaming about a stock AMD at 3.2 with 1mb L2 cache. Of course an X2 like that would be even sweeter.

Techreport (http://www.techreport.com/reviews/2005q2/athlon64-fx57/index.x?pg=15) have some benchmarks with a 4000+ v FX-57 in SLI
