What resolution do you game at and what connections does your monitor use? Also, what power supply are you using?

1920x1080 600W HDMI

There's 2 2gb models and a 1gb model. You don't really need 2GB unless you are running higher resolutions with a lot of textures, but since they all cost around the same, might as well just get 2GB. I would go for the Gigabyte OC just because factory overclocked models come with a higher binned chip.

I'd go with the Gigabyte Windforce x2 (Here's a Review I found).

At 1920x1080, you are right at the point where having more graphics memory becomes beneficial and the Gigabyte card has an excellent cooling solution. Plus, it's only a few quid more.

I'm going to go ahead and assume that your PSU is from a quality brand and has all the proper power connectors but it wouldn't hurt for you to double check before you make a purchase.

Its a Corsair 600W CX Series V2 PSU - 6x SATA 2x PCI-E is it good enough?

 

[subasteve5800]

Yeah. That PSU has more than enough power and all the connectors you'll need.

You should be good to go. Enjoy.
