Ive just wrrecked my Xbox 360 and not really wanting to get another one as pretty sure new consoles will be coming out late next year or early 2014 and will get another one then.

I want to do some PC gaming for the next 18 months and currently have system below which I got a few months ago and have not really used for gaming.

Intel I7 2700K 3.5Ghz
Asus P8Z68-V Le Z68 board
8gb ram
Asus ENGTX560 ti
Coair TX650 V2 power supply

I know the basic PC will be fine for gaming over next year or so but is the video card still going to hold up or should I upgrade. Or is the 560 ti sill an ok card for now.

Bearing in mind I will be playing on a 40 inch TV screen and as long as graphics look as good as 360 or better thats fine for me. I dont mind running games at 1080p or 720p.

Other option would be to keep 560 for now and upgrade in 6-10 months or so if that would make more sence. I just dont know much about PC graphics cards and when is best time to upgrade - price verses bang for buck.

Any advise would be great thanks and also what card I should look at upgrading to if 560 will be suffering in the future.
