Need help to choose video card upgrade

[AlexVQc]

This is my build:

CPU: Intel core 2 quad QX9650
Motherboard: Asus Striker II NSE
RAM: 8 GB DDR3 Corsair Vengeance 1600 (running at 1333)
OS: Windows 7 Ultimate
PSU: Corsair 620W (willing to upgrade if really needed)
Monitor: Dell UltraSharp U2711 (27" @ 2560*1440)
Video: BFG Geforce 260 OC

My video card is now due to an upgrade. My computer is still good (in my opinion) and with a new video card I think I would be still good for 1-2 years.

I know my current build is now a bottleneck for current video cards (I guess).

What would be the best single card my system would take (PCIe 2.0 x16 is the best my motherboard can take)? I really prefer Nvidia over ATI. I'm not really in a hurry to buy a new one (I can wait fow the 660s and 670s I guess).

I play games form World of Warcraft to Battlefield 3. And I like to play at max settings...

Thanks!

Core 2 Quad is still decent enough today for midrange cards. A 560 Ti 448 or original 560 Ti could be a good choice.

Just a week ago If I am not wrong, 560 Ti 448 used to be $20 cheaper than now.

I can get a EVGA GeForce GTX 560 Fermi 850MHZ 1024MB Superclocked for $140 (new) which seems really really cheap...

OK. I think my best bet is to wait for the 660s and 670s. The "older" ones will get lower in price I guess...

I paid $255 for an EVGA 560ti 448 with a game and before the $30 rebate. Prices on those cards are going the wrong way.

I ended up buying an MSI GeForce GTX 670 OC 1045MHZ 2GB and I'm happy with it.
