A friend of mine has a P4 3.06GHz system. He's looking at buying a 6800 GT for it, but I told him to upgrade his system because a P4 3.06GHz runs on the 533MHz bus and is too slow to really get the most out of a 6800 GT. His games will run better than his 5900 nu, but he won't get as much performance as he would with a P4 3.4 Prescott or dual-channel CPU. Should he get a new system or stick with his 5900 nu until he can upgrade?

If he's satisfied with the performance of his 5900 for now, then it might be advisable for him to hold off. With the nForce4 and SLI knocking on the door, he might want to wait for that technology, or when it comes out, pick up an AGP-based system at a lower price.

Ya thats a pretty decent cpu, at least its not one of the older ones. I know a guy who has a p4 2.2 still that came with his DeLL.

But neway a 6800GT will make his system faster im sure. If hes gonna upgrade his cpu aswell i think he would want to get a nice high end one to be more futureproof. And really theres no point in getting a brand new high end cpu if ur not gonna get a pci-e mobo aswell IMO. That stuff can add up.

Although the 800mhz htt p4s have gone down quite a bit in price. So it might be a good idea to do a smaller upgrade like that. Owell up to u guys :)

:EDIT: also id say hes well above the lowest cpu for a 6800GT right now.

It ran fine on my 2600+ and it wasnt a barton and also the 6800GT was on a 4x agp ECS mobo with 512mb pc2100 and i still scored a 10000 or more on 3dmark03 with that setup. Hell the hdd wasnt even 8mb cache

I have a P4 3.06 and the 6800 GT is great with it. I get 11442 in 3DMark03.

This I would have agreed with last month.

I have just finished running tests on HL2. It didnt matter what resolution, what settings, AA and AF at 16x or 0x. My computer gets about 90FPS on in a Timedemo from Hardcop.

Which totaly means my system is completely CPU Limited. I am also getting 1gig of sweet ass ram to test this thoery. But I am almost positive that my 6800GT is not being Pushed at all.

I got a 2.53ghz p4 but its overclocked to 3.15 right now.. runs really good.. this was a cheap ebay upgrade for my 1.6 ghz p4 and geforce 3 a few months ago.. still on same mobo!

The lowest acceptable CPU for a 6800 GT in my opinion would be around an Athlon XP 3200+ or a Pentium 4 2.8C, considering they're both stock. Mine is a bit faster, being an Athlon XP-M 2400MHz, so around a 3.0-3.2C (stock), however that's about the limit for me. I'd rather have a P4 3.0C since I could overclock that to 3.5-3.6GHz, but then again I only paid 150CAD for mine, wheareas that P4 was 310CAD at the time. :retard:

I say that your friend should keep his FX5900 for now. Maybe upgrade in 6 months to something like A64 3200+ S939 and so on.

My setup includes a p4 2.8 @ 3.0 ghz w/a 800 mhz fsb. I upgraded from a 9800 pro to a 6800gt and the change is huge in games. I think your foolish to think your buddy needs to upgrade his cpu to get an enjoyable increase from a new 6800 card. I am not sure that this post makes any sence at all it seems to be a rather :lame: point!

i have a 3.06 ghz p4 and the 6800 gt works like butter in my system.. im sure i would probably get a higher score on them 3dmarks with a better processor but as of right now im gettin around 12000 on 03 and 5000 on 05... thats with it oc'd to ultra.. point being.. my processor can still hang in there with them newer ones.. and the jump from my ti4600 to the 6800 gt was f*cking huge.. oh and with the 5900.. u can only play dx8 (i think) on hl2.. 6800 can play dx9

A 3Ghz or faster system even with a 533fsb
will run a 6800 very well.
Even if I clock my rig at the stock 2.8 my 6800 runs good.

Tell him to get a 6800 and be happy. He will love the performance. :D

hmm...my 3000+ w/1Gig 2700 is doing great....a big improvement over a 9600XT.

That CPU is fine for a GT. He can OC it later on and get some more performance out of it. 3.4ghz should be in reach easily.

Anythin from P4 2.8e GHz to 3.xe Will giv u a good performance.. if u upgrade to a GT.
Dont buy a new processor now.
Wait for a while.. I read today..nv & intel sign up a contract..through wich.. nforce chipsets will b available for intel borads..and will also support SLi.
Wait for that..Sounds good

On the other hand, I saw benchmarks at HardOCP comparing FX-53 with 2GB ram to a XP3200+ with 512MB, running Doom3 at 1280x1024.

Guess what? The humble XP3200+ actually benched *the same* as the FX-53! So even FX-53's are **GPU** limited in Doom3 at higher resolutions.

This thread is funny to me :) I'm running my 6800GT with a 1.5GHz Pentium III-based Celeron.

Yeh totaly opengl games utilize the GPU better. Like Doom3.

But HL2 (Direct3d) is just too CPU dependent. I was wondering why my mates 9800XT, is running HL2 almost as good as mine. I get it now. He has his P4 running at 3.2ghz.

Another Friend has a P4 2.0ghz and a 6800GT and he gets less FPS then the 9800XT.

So there ya go.....for HL2. You wanna have the best CPU speed you can have.

Can't say i agree with those who say that a 3.06ghz cpu is enough. I have a 2.6c@3.06 with the 800mhz bus and HT and it's dragging down my GT bigtime. In most of the games I play and at the resolutions I like my old 9700pro would have done the job just as well. To get acceptable performance from the games I actually upgraded to play (HL2, CS:S, Vampire: Bloodlines, and Doom III) I am going to have to uppgrade to a socket 939AMD 64 3200+ or better. Anything less would be throwing away the potential of the GT in my opinion. As soon as I get some cash and prices drop after xmas im jumping on the AMD bandwagon.

Well don't laugh: the PIII is a more powerful chip than the P4. (MHz for MHz that is.)

Intel really dropped the ball with the P4 imho. Unfortunately AMD failed to capitalize on it when the P4 was still struggling and Intel managed to get competitive again by increasing the amount of cache and driving up the clock speed.

But many benchmarks have shown: the P3 is intrinsically a more powerful processor.

I dig my processor. It kicks the pants off most P4's up to 2GHz or so. It can't keep up with the high MHz P4's though, and I can't get anything but SDRAM or it. So it was nice back in the day, and I've gotten a good life out of it, but it's getting a little long in the tooth.

I'll advise him to upgrade his system now. He can get much better fps. Later, he can buy another AGP-based system as an upgrade. Thanks for all the input.

I had a 9700 Pro before the 6800 GT and the GT made a very big difference to me. This is the first time I have actually been able to play games with AA and AF enabled and have it play at the resolution I like (1280x1024) without it playing like crap. I don't know about your system but mine is playing CSS, HL2, Vampire and Doom 3 pretty damn good if I may say so.

damn i wish i had a 6800gt but got no money lately :( lucky bastards :)
sorry for this bad post, im gonna sell something to get that 6800gt for this a2700+ :)

I upgraded from a FX5900 to my PNY 6800GT and saw a nice boost in performance on my P4 (2.8Ghz). However, I'm about to upgrade to PC3200 RAM and plan to OC my CPU. I'm also running my RAM in dual channel mode, which is a big benefit, IMO. I would have to say he would be better off with the 6800GT, he can always upgrade his CPU and/or Mobo later.

Actually, Anything between a 2400+ on up is acceptable for GeForce 6800GT. Even if you have something lower than that it still wouldn't hurt because you an always upgrade your PC later and stick that card right back in.

Buying GT to upgrade PC later is not really buying the card for the current CPU.

Lowest acceptable CPU could be calculated on case by case basis. The limit would naturally be where you start to get better FPS with a slower card and a new CPU using the same amount of money that the GT alone would cost.

Im sure that there are a lot of PCs out there that would benefit more from 6800NU/6600GT + 512MB RAM stick than from just 6800GT for example. Lowest acceptable CPU is a bit trickier, though, because there is more hardware than just the CPU that effect the performance.
