I'm currently running the Phenom II x4 965 alongside the GeForce GTX 460. I'm looking to upgrade my GPU soon to something a bit newer and better, but I'm concerned about whether or not my CPU will be able to cope with higher demands from a new graphics card. I've got a PSU of 650W- I believe it's a Corsair one but I can't remember how to check- so I think my power supply should cope fine with a new card, it's just my processor that I'm worried might be issue.
I should note that I'm not as in-the-know about these things as I was a year or two ago, so simple English please.
You can use a better card and gaming on a single monitor at 1080p should be fine you may want to OC the CPU though
My monitor itself isn't that large so I won't be playing at those resolutions. So I'll be fine with a card such as the GTX 560?
