Track, I don't know if that's just a fanboi axe you're grinding or what your issue is, but I am not going to get into some kind of battle with someone so hell bent on spreading disinformation.
The 6950 and the 560Ti are so close in performance, and trade off performance leads from game to game, that it's a case of personal preference that no one who is being honest will ever notice in real world play, unless they are running benchmarking software in every game/application.
I will say, if you are buying a GPU for one specific game you should check benchmarks for that game. And in this case, instead of just shooting from your backside like Track is, here are some actual benchmarks from a trusted source (attached):
A caveat to the benches - that's a stock comparison. The Ti tested is @ 822Mhz, and the 6950 doesnt have the full 1536 shaders unlocked. Ti's beings old these days are almost all clocked significantly higher (usually about 900 MHz like mine), and can be pushed to about 1GHz (like mine can). Likewise, the 6950's locked shaders can sometimes be unlocked, and it can be overclocked some as well. Also, there are 2GB versions of both cards, which will help with higher resolutions.
Having said all that, the general performance trend is that the Ti is a hair faster at lower resolutions and the 6950, at least in these tests, was faster at higher res, with 1080 being the breakeven point in performance.
That's complete overkill for a response to your question/dilemma, but I get sick of folks like Track coming on here with an agenda.
[edit - LMAO - I gess it would help to label each card in that screencap - sorry I cant figure out how to manipulate the GPU bench for a single game and 2 cards. The blue one is the Ti, the black bar is the 6950, but the fact that they have to be identified is kind of the point. It's not worth stressing over. They're too close. Find a good deal on either and pat yourself on the back for a good purchase.Edited by The Advocate - 10/2/11 at 7:06am
