My card is somewhere around 9 from the "top". The card i'm looking at, is the GeForce 560 TI. 5 spaces ahead of my 8800GTS.
Where i'm stumped though, is my 8800GTS's are in SLI, so they're significantly more powerful then just a single 8800GTS 512. It says not to upgrade within 3 teirs, because you may not feel a improvement. Well I want to feel an improvement.
Will the GeForce 560 TI out perform my SLI 8800GTS 512's?
I want everything on this system to outperform my old, with still room to grow. (space for more memory, i can buy a better CPU if i wanted it, add in a second video card, so on and so forth. )
(also i do overclock quiet a bit, right now my settings are stock to get a baseline. also my memory is ***, i know. )
If you really want DX11 and troll on the forums because you can't play all games with maxed eyecandy, go ahead and buy the a 560 or two. If you want to save some cash, don't upgrade since you won't notice much of a real world difference and you'll be disappointed.
It would be a significant upgrade, but it would definitely be the weak part of that build.
To remove all doubt go with a GTX570. Get yourself phat, good quality psu so you can add another down the road and for overclocking. You won't need to overclock your cpu for one GTX570, but for 2 you will.
