question i got for you gurus is :

Just needs to be another 1Gb GTX560ti, the drivers will slow the faster card to the same level as the slowest.

the drivers will slow the faster card to the same level as the slowest.

You can also OC the cards so they're both faster using MSI afterburner

Do you need the graphics any higher? If not and it's playing fine stick to what you got You bought nice rig tho so i understand you wanting to upgrade to the best.

If you added another 560Ti you would see a significant rise in fps in BF3 even with most settings at ultra and I think that PSU would be able to run it. The question is whether you are happy with the current performance, if you are you could always wait and get another later when games get even more demanding.

Also it would not make a huge difference if you were to get some arctic silver but you may see a few degrees less. I would leave it unless you are going to buy a new CPU cooler as it's a lot of hassle to take off the current one for a few degrees.
