X1800 Xfire or single X1900XTX?

What would be the best upgrade?

I already have an X1800XT and my screen runs at 1680x1050, so all gaming would be based on that resolution.

With games like Oblivion on the way, 1680x1050 with AA and AF might push my X1800XT.

Nah, I just have the slave.

No problem as far as power is concerned. I have an Enermax Liberty 620 watt and am even contemplating putting my gear back into a CM Stacker, which I was using with a 2nd system. With the Stacker I could use 2 PSUs, giving me over 1200 watts to play with.

I'm just playing WoW a lot at the moment, but wouldn't even some current games benefit from one of the two upgrades. My X1800XT easily runs WoW with all settings maxed out....but then WoW is known not to have very heavy system requirements.

So should I be asking: will I benefit when playing COD2/Serious Sam2 at 1680x1050, all setting maxed out and high AA/AF?

I have the Asus Xfire mobo, still boxed until I decide which GPU to get.

Actually, is there any update on the Agea physics card? That might be a factor as well. As far as available PCI slots are concerned, I can't see how an Xfire setup would work with a PCI physics card and PCI sound card.
