Is this a good upgrade?

[TeeJay]

I've done upgrading everything in my system except for my GFX, and maybe my motherboard, I'm not really sure...I find it good...

Anyway, what I can find that is suitable in price for me in my country is a GTX 275...My country sells PC Hardware for x2 the price in the US...As you can see, this is the card I'm willing to get... http://www.advantionline.com/EVGA-N...6MB-DDR3-2DVI-PCI-Express-2.0-Video-Card.html

Would this be a good upgrade...Going from a GTS 250 to a GTX 275?

I'll be playing games such as Crysis Warhead, Batman, you know...all these new games

Oh yeah, is my 660 PSU good enough to take that GTS 275?

EDIT: I was looking around and found this Sapphire 5850( http://www.advantionline.com/SAPPHI...ire-Supported-Video-Card-w-ATI-Eyefinity.html )...Which would be better for me?

A 5850 would probably be better but it's going to depend on whatever is cheaper in your country. Both would be a decent upgrade from your GTS 250.

Your 660 watt is more than enough for that system with a single GTX 275, although to be sure what model is it?
