An AMD Athlon Barton 3000XP 400FSB

or a

P4 3.0 ghz 800FSB

Which would you choose for gaming?

The latter. 800 FSB is the kicker.

Overall I'd say the P4 is a slightly faster CPU, but the XP 3000+ is quite a bit cheaper. For gaming though, they are very close and by far your main bottleneck with either of these CPUs is going to be the video card. They both have the necessary power to push a Radeon 9800 Pro or GeForce FX 5900 card near its limits. There are certain games that are faster on P4s (Quake 3, Ghost Recon, Jedi Knight 2) and others that are faster on Athlons (Serious Sam 1 & 2, Unreal Tournament 2003), but overall those two CPUs are close for gaming.

You are going to need DDR400 (PC3200) memory for both for best performance. AMD recently adjusted the speed of the 3000+ model to better compete with the 'C' (800 MHz FSB) P4s. The original 3000+ was a 2167 MHz 333 MHz FSB part, the new 3000+ is a 2100 MHz 400 MHz FSB part and is significantly faster than the old 3000+ overall.

Either of these will be paired with

Radeon 9800XT

and

1GB OCZ Dual Channel DDR4200 RAM

I'm just having trouble deciding which CPU to go with. I have both here, the AMD with an Nforce2 board and the P4 with the Canterwood 875P.

Tough call from a gaming standpoint alone. I'd say if you do a lot of video encoding, go with the P4. Engineering/scientific apps, go with the Athlon.

If you're going for a top-end CPU, you should consider the AMD Opteron or FX chips.

Guys...the measly 400 FSB on the Athlon will make a big difference. It might be cheaper, but it's going to be slower for high-powered games like AH. The video card is not always the bottleneck.

The Athlon FX seems OK, but too expensive. Once they drop the price it will become more interesting.

The best bang for the buck right now is an overclocked 2.4C P4, with PC4200 RAM. The 2.4C will easily clock up to 3.2+, and you will get a 1066+ FSB with that. That will beat or at least match a stock Athlon FX, for games.

Ok i have a 2.4c cpu it overclocks stable to 3.0G and by no means will every 2.4c "easily" overclock to 3.2g.
I am at 1:1 ratio at 1004 mhz FSB and memory speed.

However having said that if you check the AH2 beta 4 thread i think you will see i am getting the best frame rates by a large margin, using a 9800 pro.

However i do not know whether anybody using a 3000 XP has posted any results.

You may need to raise your Vcore or DRAM voltage, or you may not have adequate cooling, or your RAM ma not be able to keep up. Try a 3:2 OC, and see how far you can go. Or perhaps you got unlucky, but given the ad hoc stats I'd say that was unlikely. It is well known that almost all recent canterwood P4s clock up to 3.5 or 3.6 GHz; hence my comment that it easily clocks up to 3.2+.

I see you have a Max3 board. I have the same board. That board has a well known bug which prevents proper operation when you set Vdimm > 2.8. This can limit how much your memory overclocks. If you set the ratio to 3:2, you'll probably find that the processor has a lot more headroom.

Go to the abit forums (abit-usa.com) to see more about the max3 problem.

I used the Abit max3 board and with proper cooling you can see the results

mold · « **Reply #11 on:** November 19, 2003, 03:05:18 PM »

Cool. What RAM and Vdimm settings, mrblack?

mrblack · « **Reply #12 on:** November 19, 2003, 03:08:38 PM »

Mushkin pc3500 with the BH-5 chips.
Ram settings where at spd voltage at 2.8
I was using the prometiea phase change cooling system

you should read THIS thread:http://www.hitechcreations.com/forums/showthread.php?s=&threadid=99359

the 400 vs 800 thing is better explained.

800fsb doesn't always mean faster if the architecture is different.

I heard about that mold. is that all the max3 boards or just some of them. I thought that there were 'broken' oards and good ones. I havnt testem mine yet, but I sure hope I didnt get a lemon?
