If you want a good budget card that will handle cod5 go for an ati 4830, the performance is not far behind a 4850 at stock speeds, but the core overclocks well, and it gives nigh on the same performance as the 4850 when overclocked. the drop from 800 shaders to 640 shaders doesnt seem to make much difference.

The 8400GS is a terrible graphics card for games. To get a smooth frame rate at anything above minimum graphics settings, Call of Duty World at War requires something like an 8600GT or 9500GT. However, your best bet now is to find an HD4650 or HD4670, the former will beat the 9500GT and will certainly play COD:WAW at reduced settings, the latter can actually run the game at pretty much maximum and get a relatively smooth frame rate at 1280x1024, and only costs $80, plus will fit in any case and run on pretty much any power supply.
The HD4830 mentioned before will run even better, but needs a strong power supply, and costs over 100 dollars.

ck: Interesting that the motherboards proved very problematic for them to get to a good overclock, and that they only found a testable setting at 3.8Ghz. One wonders how they backup their claim of it being stable at 4Ghz if they couldn't even install an OS.
Overall, in the games that matter, that's a 40% performance boost on the stock 9950, which isn't bad, but puts the overclocked Phenom II about the same as a stock Q9650. Impressive as that is, the Q8200 is probably the only Core 2 Quad that would have any difficulty matching that.

Yeh lack of the needed bios update seems to have been the biggest issue, by the way the motherboard fried it seems like a newer bios might handle the voltages better, and maybe even make it run cooler.
still a vast improvement on the old phenoms. just nice to see that they do have a little fight left lol.

4830's are worth upgrading powersupply for. I get a solid 90+ fps in cod 4 1680 x 1050 full everything. thats with core @ 700 mem @ 925 :) not much give in the mem with stock cooling, getting a zalman so that should help it :)

If you can upgrade the power supply. For all we know this guy may have a prebuilt system, or he may have a 17-19" monitor. If he does, there's not much need to get anything better than a 4670 for anything bar maybe Crysis, and he may not be able to upgrade his PSU for one anyway. I'm well aware of how much better the 4830 is, but not everybody can have, or needs one.

Sam,
I was wondering about that 4GHz myself. If you can't load an OS, how do you know it's stable? Still, it bodes well for the coming of the low wattage HKMG Metal Gate Transistors for the Phenom IIs. That will raise AMD fan's excitement level considerably! I do know this, Intel is worried, very worried!

Best Regards,
Russ

The 2.7Ghz Phenom IIs look like they'll be about 10% behind the 2.66Ghz Core 2 Quad. On that basis, a 4Ghz Phenom II will do very well indeed, in arithmetics it certainly won't catch the i7s at any clock above stock, but it'll be a good competitor for Core 2 Quads, if anything that powers/cools that 200+ Watt monster can stay the course.

Sam,
That's where the Acc and Overdrive come in!
http://www.pcper.com/article.php?type=expert&aid=612&pid=2

Phenom II will consume even less power and when the HKMG is ready, even less than that!

All that is though, is overclocking without voltage addition, or undervolting, which is what all CPUs can do, it's just an automated process. They've got an extra 200mhz out of the CPU like that. Core 2 Quads often gain 500-600mhz before needing extra voltage.

Sam,
It's a bit more than that, but AMD is being very vague about all that it actually does do! They tested a 9850 Phenom and overclocked it to 3.0, which was as far as they could get it to go. After they enabled the ACC and turned on the overdrive they were able to get it to 3.4GHz stable with the same voltage. The CPU is directly connected to the SB, but again AMD is being very vague about what all of that does.

Overall they were able to overclock it 900MHz without using any more power than it required to overclock it 500MHz.

Which basically, is a bit of a catch-up move. A welcome one certainly, but a catch-up nonetheless.

Anything around a 9800GT or HD4850 and up, ideally with 1Gb Vram. Think the game requires 1.5Gb for full textures and view distance! Although 850Mb+ (I.e GTX260) will let you max the textures but with about 1/2 view distance. A 512Mb frame buffer will mean medium textures and view distance <40/100.
Edit: worth bearing in mind though that the console versions apparantly have view distance of 25/100 and detail distance of 20, so it should still look as good/better than the console versions with a good 512Mb card.

Q9550 @ 3.4Ghz-1.275v & TRUE, Asus P5N-T Deluxe, 4Gb Dominator 1066 (5-5-5-15), Inno3d OC 8800GTs in SLi with TT Duorbs, 580w 5.1 Setup, 2x DVD-RAM, 320&160Gb SATA2 HDDs, 17" 3ms Hyundai TFT, 700w Jeantech PSU.

Actually from what I've read it's more like 10 and 12. You don't need much to surpass the console graphics, but just as well really, as you need a very beefy CPU to run the game, as most of the effects are processed by the CPU, not the graphics card.

So basically the Q6600 @ 3.0GHz and a 8600GT or a 9800GT, which is better for the money, would work fine. I don't care about running games at max, I have a PS3 for that.

I assume you meant 8800GT vs 9600GT. The 8600 and 9800 are miles apart!

Completely different cards but neither of them is going to play a lot of games. The 8600GT has only 32 stream processors and is fine for surfing the net and word processing. The 9600GT has 64 stream processors and will play some low demanding games probably mostly older ones. To get anything that will play a variety of games with Nvidia you really should be looking at cards with 96 to 112 stream processors as the bare minimum. For that kind of money you would do much better with an ATI solution unless you're folding.:D

To be fair, the 9600GT isn't that bad. Don't you have an HD3870 Soph? It's no slower than that.

I do have an HD 3870 and it would walk all over the 9600GT. I also have an 8800GS (96 stream processors) which is considerably faster than the 9600GT (64 stream processors) and the 3870 will easily beat that too. I have two 8800GTS (G92) cards (128 stream processors) and they are in about the same range as the the HD 3870. My fastest card currently is the GTX260 with 194 stream processors.

Actually, The 9600GT and 8800GS are about 10% behind the HD3870, that's hardly being walked all over.

I never said that the HD 3870 would walk all over the 8800GS although even 10% is significant, I said that it would walk all over the 9600GT which is slower than the 8800GS. In test that I've seen even the HD 3850 beats the 9600GT. Now my two GTS (G92) cards will beat my HD 3870 by a fair margin but then they are the exact same card as the 9800GTX. On average I think that the HD 3870 is probably closer to 15% to 20% faster depending on the game than the 9600GT. Now that's a walk.

OK, Sam I'm yanking your chain a bit. I was wondering why you didn't ask me why I had all those Nvidia cards. One thing for certain is that the GTS (G2)cards are incredible overclockers.

10-20% does not stop it from being a good card though, to say you can only play older games at medium detail is unfair. See my post in the graphics card thread for more details.
