Im considering upgrading from my GeForce 7900GT/OC GDDR3 256 to a 8800 GTS GDDR3 320. Now, should I do this because the price im getting for the 8800 is $270 from tigerdirect.com. Im basicly just woundering how great the difference between the two cards are. I already know about the shader 4 and DX10, etc....
I'm not looking to get a GTX or any of the cards that are comming out because you know what? I don't have $700+ to just throw out the window on a card. Which is why im asking about the 8800 GTS for the DX10 compatibility and such
Some, like Oblivion, will see dramatic improvement, others will only see slight improvements.
As for the DX10 component, there's nothing really compelling yet to say how it will handle DX10, and whether it would be worth the upgrade. IMO in games that have a DX10 option, the DX9 path will be very shader intensive like Oblivion (as we saw in COH) and that type of game will play well to an 8800 even in DX9 mode.
If you don't NEED to buy now, then I'd say wait, but if you do play games like Oblivion, then check their benchies and see if the performance or settings difference (Oblivion noticeably adds HDR+AA and better AF filtering) .
There's places it will shine and others it will be only mildly different. I'd say if you don't get a compelling reason for yourself, then wait for that compelling reason.
As always, just my view from the cheap seats and my two frames' worth.
