The 9800GTX is about as powerful as an 8800GTX if that puts it into perspective.

To put it into better perspective, the 9800GTX is less than 5% faster than the 8800GTS; yet it costs around 33% more.
And saying it "overclocks better" is a little misleading. They both overclock very well. The 9800GTX starts at higher clocks; so (from what I've seen) it subsequently achieves slightly higher maximum frequencies. But that's about it. They use the same G92 core (probably "binned" higher for the 9800GTX). The ending difference isn't huge by any means. The thing is; you're still likely to see around the same 5% performance difference when both are overclocked to their max.
The reason why the memory achieves higher frequencies on the 9800GTX is simply because the timings have been loosened (sorry I can't find the link ATM). So while the GTX is generally capable of higher memory frequencies, the memory actually performs better on the GTS at the same frequency. This has been proven by
Expreview. To demonstrate, they overclocked the 8800GTS G92 and 9800GTX to the EXACT same clocks - and the 8800GTS G92, on average, performed
better.
So when considering the 8800GTS G92 vs. 9800GTX, you have to ask yourself - is 75 to 100 dollars with a 5% performance increase - and could that money be better spent elsewhere? If you're building a new rig (and actually have a budget limit), you'd probably be able to increase the performance more than 5% by putting the 75 bucks towards a different component. That would make buying a 9800GTX completely redundant.
Oh, and the 8800GTX. It usually outperforms both the 8800GTS and 9800GTX at high res + AA/AF. There have also been accounts of less "lags" (frame rate drops & minimum frames) when playing games, probably due to the superior 768MB of 384-bit memory. They aren't as good at low res & no AA/AF, however. But the overall difference is minimal. Since they're getting much more scarce, if you can find one in the low-$300 range you're lucky. So the 8800GTX price-to-performance ratio ATM is rather poor, and not really worth it for most.
