I posted a topic earlier about whether or not to upgrade my gpu at this current time. And i was given a link to a 7870, which obviously intrigued me, I went to the link and it's selling for £130, compared to the normal £204, I know that that's extremely cheap for the card but would the upgrade to the 7870 be worth it? Thats my main question, would it be a noticeable difference to my 560ti?
If you are unhappy with your current performance then yes other wise you can always just save the money and buy a different card later. Yes the 7870 is better but if you are content with your 560ti there is not really a reason to upgrade.
