Re: Justifying A GeForce GTX 275
Honestly, guys I've tested games with SLi off and a GTX 260 Core 216 @ about 660|2300 pushes everything well @ 1920x unless you are running very high levels of AA. Yes, there are exceptions like if you try to run Crysis all VH. You could do it fine with a mix of VH and High though.
I'd say buy what you like. You aren't going to feel the FPS difference between a stock 275 and an overclocked HD 4890.
If you get the 275 if leaves the door open for SLi and PhysX. Again, I've had way better luck with nVidia multi-GPU. With Crossfire; profiles were late, sometimes they'd break old game profiles with new drivers, and I had more odd graphics glitches with it. Also I like that nVidia lets you assign your rendering mode; AFR1, AFR2, or SFR.
The above isn't the "objective truth", I'm just relating my experiences and opinion.
