>Omen< The 4850 is priced well but wouldn't give you much of a boost from what you have.
I have to disagree with you there, the 4850 is faster (or ties with) the 9800GTX in pretty much everything, so it should out perform a old 320MB GTS by a decent amount.
Yes, Im getting a new system with a superclocked 8800GT
I would wait on the GT and consider the faster Radeon 4850, or seeing how the 4870's do once they are released.
I've not seen it compared to the 8800GTS 320, but I have seen it compared to the slightly slower 8800GT and even it was not enough of an increase to be worth going to a whole nw GPU. My idea of a practical upgrade is getting a significant increase in FPS. Unless of course it can be had at refurbed product pricing, which simply won't be available for a while on that card. For instance it's probably not even as much FPS increase as I got in going from an X800XT to an X1950Pro, but I got my X1950Pro for only $109 refurbed several months ago. If I'd paid normal pricing on the XC1950Pro I'd be wanting a faster boost than I got.
Yeah, I concur with others: Your system looks fine.
Even the latest video-card offerings won't be dramatically better than your GTS unless you drop some serious coin on dual card setups. Even then, it'd really only be worth it if you run at insanely high resolutions.
FYI - The 4850 (just like the 9800GTX) is only going to be like a 30% performance increase over that GTS. As Omen mentioned, kind of not worth spending $170-$200 just for that.
I think for upgrades, I'm gonna sit this round out and stick to what I have in my sig for another year. It's quite similar to your setup and still performs fine for me in games, benchies (12k in 3D06) and other mundane tasks like pr0n surfing. :p Besides, all my money goes in the gas tank now.
