How much of a performance increase should I expect when I upgrade to a 7800GT or x1800XL? How much of a step up from my 16/6 6800GS would these cards be? (Only reason why I may get the XL is for ATI's superb AA renderation compared to nVidia's crappy AA renderation.)

Um, ATI AA is much better than nVidia AA, I know this because I upgraded from an x850 XTPE, and I thought there was something wrong with my video card when I tried to pump the AA up in CS;S, nVidia AA isn't as good looking as ATI AA, it is a FACT.

But get back on topic, please.

Benchmarks have shown if you up the voltage on GS' and overclock 'em to poop they can actually match 7800's in benchies. So not much? Well not enough to actually give a valid reason for an upgrade in my opinion unless you get an upper model 7800. A GT perhaps?

Can I see some proof?

Not true, I tried it it, not true. I tried running my voltage at 1.6v on my GS, allowed for a higher core OC of about 10MHz, and lowered my voltage down to 1.4v, and that allowed for a 5MHz higher OC from the 1.6V BIOS. Read the first post, I said 7800GT, not GS.

I'm upgrading to PCI-E.

Edit:
Nvidia 7800GTX 512: http://www.firingsquad.com/media/hir.../images/02.png
x1800XT: http://www.firingsquad.com/media/hir.../images/01.png
The 7800GTX does have higher AA rates than the 6800GT, the 6800GT AA looks like crap compared to the x850 XTPE's, I know this because I have owned 2 x850 XTPE's, and 2 6800GT's (GS is unlocked to GT, so I consider it a GT because it uses the same core, and is pretty much identical, besides the GS's crappy OCing capabilities)

Read the above link.
Edit 2: the 7800 series cards only look as good as the x1800 with SUPER AA, not regular. When it comes to regluar AA, the x1800 is the true winner. Super AA is an FPS monster, therefore I will not use it.
Read the whole article, please. I'm not trying to flame.

About that whole AA thing, you remember the long thread about how ATI payed off valve to make it so nvidia cards cannot run AA in source. YiffyGriffy proved that they are the exact same. You have to set the AA in your nvidia device manager instead of what the software sets it too.

You would see a major difference. The jump from agp to pci-e should provide a great improvement. a 7800GT compared to a 6800GS agp I would expect a big jump. There are probably some benchmarks of the 2 somewhere.

That does explain a lot, and seems believable.
But ATI AA is still a little better when it comes to regular AA, but nVidia is the winner of the super AA title.

not many researchers in here i see. proof is not usually attained by one experiment by one individual. you need multiple instances. folks what you are talking about is YOUR experience. when you say something is fact please take it seriously, others are reading this and may think you know what your talking about.

There was a chart that showed performance increase for changing video cards... it didn't have the 6800GS, but since yours is unlocked, it's basicly a GT. If my memory doesn't fail me (which it usually does
) I think that was something on the order of 27% increase in performance.

Just to clear some things up

Let me guess...u put it on max in css which is x6AA? Nvidia don't support x6AA just x2,x4,x8. Stick it on x4AA in game and u'll see it working fine.

Same solution as above...just put it on x4AA in game, no need to change anything manually on the driver level

In response to the original post, getting a 7800GT will mean jumping from playable to smooth (40fps) in a new game like Age of Empires 3 based on the benches here http://www.tomshardware.com/2005/12/...iii/page5.html.

The 1800XL gets beaten by 10fps a lot but I suspect those benches are all OpenGL anyway (which Nvidia get better performance on). Look at some DirectX benches and see if they can sway you to an X1800XL, also consider whether u play OpenGL or DirectX games more.
