Your CPU is the next logical bottleneck, but I'm not sure that it'd be worthwhile to move to a socket A 3200+. You'd probably be better served to switch to a socket 754 of 939 platform, but that would require both a new motherboard and CPU. S754 won't perform as well as 939, but should be substantially cheaper. I have no idea what the parts market is like for you, though, so I can't really tell you what exactly to look at.

Correct me if I'm wrong... but if you increase your AGP bus speed, lower your CPU multiplyer, and increase the FSB wont that help the card run a little faster? But like mr C3(lotsofnumbers) says, the best and most permanent fix would be to upgrade your motherboard and processor to a s939 A64.

Corrected. You'll more than likely crash almost instantly. Very, very few boards could handle even a 1MHz increase in AGP/PCI frequency. The CPU would still be a significant bottleneck anyway.

Really??? I have a proprietary Shuttle motherboard and I took mine from 2500MHz to a little over 2550MHz and it didnt crash... it was only long enough to run one of the little demo movies in 3Dmark05 though...

Are the bartons like the celerons for AMD? I got a 2.4ghz P4(mobo has it locked:()and I am bottlenecked, not as much as you are though, CS:S gets around 70-100 with a BFG 6800gt oc 256mb.

That's your CPU. The AGP bus runs at 66.6MHz, PCI at 33.3MHz. Should've probably been clearer: it's next to impossible to overclock the AGP/PCI bus without crashing badly (I've heard unconfirmed stories of lost cards and slots to this sort of activity). @spo8~ Because the 3DMark programs are very GPU intensive, and not terribly sensitive to CPU and memory in the final score. Try running PCMark2004 and see how you do. @Pethegreatâ„¢~ Actually, Barton was the core to have back in the socket A days. It was the last core to be sold in that package, and was quite a performer. It was also the only AthlonXP to come in 400MHz FSB versions.

In the clock control page of nTune, the bar for PCI express bus says 2500MHz... I guess I just assumed that the AGP bus would be close to as fast and maybe as easy to overclock.

oh ok, its like the northwood core in the 478 p4's then. Could slow ram/single channel ram hold him back? Spo8, what is the speed of your ram?
