Upgrading to GTX 760 4GB

[joshm509]

Ok so since I have some extra cash from the holidays, I'm looking to upgrade my Graphics Card. I currently have a Radeon HD 6870 and am running it via a rosewill capstone 450 psu. My tower/fans are still the stock models.

I'm considering upgrading to either a GTX 760 or 770, but was not sure of the overall upgrade from one to the other. If i get the 760, I'll be getting the 4GB version as its only an extra $40. I realize that I'm also going to have to upgrade my other stuff as well. This is what I've come up with so far:

Graphics Card: http://www.newegg.com/Product/Product.aspx?Item=N82E16814130949
PSU: http://www.newegg.com/Product/Product.aspx?Item=17-182-073
Case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811147153

My CPU is an i7-2600 3.4ghz. Will these upgrades be sufficient to run everything at the appropriate temperatures? I was also considering:

PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010&SortField=0&SummaryType=0&PageSize=10&SelectedRating=-1&VideoOnlyMark=False&IsFeedbackTab=true#scrollFullInfo

Case: http://www.newegg.com/Product/Product.aspx?Item=N82E16811119197

I'm just not sure if it is necessary for me to get the more expensive case/psu, and I wanted to make sure I'm upgrading everything appropriately.

Thanks for taking the time to help!

If in the future you want to add a second 760 to your system... you will definitely want a decent 750w power supply or higher and having the 4gb version of this card will help a lot too as the peformance of 760sli can easily run 3x1080p or a single 1440/1600p monitor and vram definite becomes an issue at those levels.
